py-networkx: updated to 2.3

Announcement: NetworkX 2.3
==========================
We're happy to announce the release of NetworkX 2.3!
NetworkX is a Python package for the creation, manipulation, and study of the
structure, dynamics, and functions of complex networks.

For more information, please visit our website <http://networkx.github.io/>_
and our gallery of examples
<https://networkx.github.io/documentation/latest/auto_examples/index.html>_.
Please send comments and questions to the networkx-discuss mailing list
<http://groups.google.com/group/networkx-discuss>_.

Highlights
----------
This release is the result of 6 months of work with over 92 pull requests by
30 contributors. Highlights include:

- Dropped support for Python 2. We are no longer supporting Python 2.7 and we will
  start changing code to take advantage of Python 3 features we couldn't before.
- Added some Moral Graph analysis functions.
- Enable matplotlib drawing using curved arrows via connectionstyle parameter.
- Remove ticks and axes labels from matplotlib plots.
- Two new generators of Harary Graphs.
- Added Dual Barabasi-Albert model
- Added VoteRank algorithm
- Added Equitable coloring algorithms
- Added planar layout algorithms
- Les Miserables network example
- Javascript example update

Improvements
------------
- Change default colors to be color-blind friendly
- Many bug fixes and documentation improvements
- Speed up of simple_cycles
- Improvements for reading various formats like GML, GEXF, Graphml
- Allow subclassing to access node_attr_dict_factory


API Changes
-----------
- The G.fresh_copy() mechanism for creating an empty_graph of the same
  type (introduced in v2.0) does not playing nicely with pickle and others.
  So, we have removed the code that caused a need for that. Instead you
  should use the more natural G.__class__() syntax to get an empty_graph
  of the same type as G.

Deprecations
------------
- The Graph.fresh_copy() method should now use Graph.__class__()
- ReverseView class removed in favor of reverse_view() function.

py-networkx: updated to 2.2

2.2:
This release is the result of 8 months of work with over 149 commits by
58 contributors. Highlights include:
- Add support for Python 3.7. This is the last release to support Python 2.
- Uniform random number generator (RNG) handling which defaults to global
  RNGs but allows specification of a single RNG for all random numbers in NX.
- Improved GraphViews to ease subclassing and remove cyclic references
  which caused trouble with deepcopy and pickle.
- New Graph method `G.update(H)`

py-networkx: updated to 2.1

NetworkX 2.1

Highlights
This release is the result of four months of work with 75 pull requests by
37 contributors. Highlights include:

  - Arrows for drawing DiGraph edges are vastly improved!
    And an example to show them.

  - More than 12 new functions for graph generation, manipulation and/or
    new graph algorithms.

    - Add a large clique size heuristic function
    - Add rooted product function
    - Label Propagation Community Detection
    - Minimum cycle basis
    - Add Mycielski Operator
    - Adds prefix_tree, dag_to_branching, and example.
    - Add inverse_line_graph generator
    - Steiner tree and metric closure.
    - Add flow based node and edge disjoint paths.
    - Update geometric networks with new models
    - Graph edit distance
    - Added function for finding a k-edge-augmentation

  - G.name is no longer processed by graph operators. It remains as a
    property mechanism to access ``G.graph['name']`` but the user is in
    charge of updating or changing it for copies, subgraphs, unions and
    other graph operations.

Improvements
  - Many bug fixes, documentation changes.
  - Speed improvements especially for subgraphs.
  - Changed input variable names for functions using ``**kwds``
    to avoid name collisions -- especially ``add_node``
  - New examples for arrows and spectral embedding of the grid graph.

    [#1750] Arguments center and scale are now available for all layout functions. The defaul values revert to the v1.9 values (center is the origin for circular layouts and domain is [0, scale) for others.
    [#1924] Replace pydot with pydotplus for drawing with the pydot interface.
    [#1888] Replace support for Python3.2 with support for Python 3.5.

Update py-networkx to 1.10, based on PR 50383 by Derouiche.

API changes

    [#1501] connected_components, weakly_connected_components, and strongly_connected_components return now a generator of sets of nodes. Previously the generator was of lists of nodes. This PR also refactored the connected_components and weakly_connected_components implementations making them faster, especially for large graphs.
    [#1547] The func_iter functions in Di/Multi/Graphs classes are slated for removal in NetworkX 2.0 release. func will behave like func_iter and return an iterator instead of list. These functions are deprecated in NetworkX 1.10 release.

New functionalities

    [#823] A enumerate_all_cliques function is added in the clique package (networkx.algorithms.clique) for enumerating all cliques (including nonmaximal ones) of undirected graphs.
    [#1105] A coloring package (networkx.algorithms.coloring) is created for graph coloring algorithms. Initially, a greedy_color function is provided for coloring graphs using various greedy heuristics.
    [#1193] A new generator edge_dfs, added to networkx.algorithms.traversal, implements a depth-first traversal of the edges in a graph. This complements functionality provided by a depth-first traversal of the nodes in a graph. For multigraphs, it allows the user to know precisely which edges were followed in a traversal. All NetworkX graph types are supported. A traversal can also reverse edge orientations or ignore them.
    [#1194] A find_cycle function is added to the networkx.algorithms.cycles package to find a cycle in a graph. Edge orientations can be optionally reversed or ignored.
    [#1210] Add a random generator for the duplication-divergence model.
    [#1241] A new networkx.algorithms.dominance package is added for dominance/dominator algorithms on directed graphs. It contains a immediate_dominators function for computing immediate dominators/dominator trees and a dominance_frontiers function for computing dominance frontiers.
    [#1269] The GML reader/parser and writer/generator are rewritten to remove the dependence on pyparsing and enable handling of arbitrary graph data.
    [#1280] The network simplex method in the networkx.algorithms.flow package is rewritten to improve its performance and support multi- and disconnected networks. For some cases, the new implementation is two or three orders of magnitude faster than the old implementation.
    [#1286] Added the Margulis„ŗŇ®abber„ŗŇ®alil graph to networkx.generators.
    [#1306] Added the chordal p-cycle graph, a mildly explicit algebraic construction of a family of 3-regular expander graphs. Also, moves both the existing expander graph generator function (for the Margulis-Gabber-Galil expander) and the new chordal cycle graph function to a new module, networkx.generators.expanders.
    [#1314] Allow overwriting of base class dict with dict-like: OrderedGraph, ThinGraph, LogGraph, etc.
    [#1321] Added to_pandas_dataframe and from_pandas_dataframe.
    [#1322] Added the Hopcroft„ŗҨarp algorithm for finding a maximum cardinality matching in bipartite graphs.
    [#1336] Expanded data keyword in G.edges and added default keyword.
    [#1338] Added support for finding optimum branchings and arborescences.
    [#1340] Added a from_pandas_dataframe function that accepts Pandas DataFrames and returns a new graph object. At a minimum, the DataFrame must have two columns, which define the nodes that make up an edge. However, the function can also process an arbitrary number of additional columns as edge attributes, such as „ŗŌōeight„ŗ
    [#1354] Expanded layout functions to add flexibility for drawing subsets of nodes with distinct layouts and for centering each layout around given coordinates.
    [#1356] Added ordered variants of default graph class.
    [#1360] Added harmonic centrality to network.algorithms.centrality.
    [#1390] The generators.bipartite have been moved to algorithms.bipartite.generators. The functions are not imported in the main namespace, so to use it, the bipartite package has to be imported.
    [#1391] Added Kanevsky„ŗ—‘ algorithm for finding all minimum-size separating node sets in an undirected graph. It is implemented as a generator of node cut sets.
    [#1399] Added power function for simple graphs
    [#1405] Added fast approximation for node connectivity based on White and Newman„ŗ—‘ approximation algorithm for finding node independent paths between two nodes.
    [#1413] Added transitive closure and antichains function for directed acyclic graphs in algorithms.dag. The antichains function was contributed by Peter Jipsen and Franco Saliola and originally developed for the SAGE project.
    [#1425] Added generator function for the complete multipartite graph.
    [#1427] Added nonisomorphic trees generator.
    [#1436] Added a generator function for circulant graphs to the networkx.generators.classic module.
    [#1437] Added function for computing quotient graphs; also created a new module, networkx.algorithms.minors.
    [#1438] Added longest_path and longest_path_length for DAG.
    [#1439] Added node and edge contraction functions to networkx.algorithms.minors.
    [#1445] Added a new modularity matrix module to networkx.linalg, and associated spectrum functions to the networkx.linalg.spectrum module.
    [#1447] Added function to generate all simple paths starting with the shortest ones based on Yen„ŗ—‘ algorithm for finding k shortest paths at algorithms.simple_paths.
    [#1455] Added the directed modularity matrix to the networkx.linalg.modularity_matrix module.
    [#1474] Adds triadic_census function; also creates a new module, networkx.algorithms.triads.
    [#1476] Adds functions for testing if a graph has weighted or negatively weighted edges. Also adds a function for testing if a graph is empty. These are is_weighted, is_negatively_weighted, and is_empty.
    [#1481] Added Johnson„ŗ—‘ algorithm; one more algorithm for shortest paths. It solves all pairs shortest path problem. This is johnson at algorithms.shortest_paths
    [#1414] Added Moody and White algorithm for identifying k_components in a graph, which is based on Kanevsky„ŗ—‘ algorithm for finding all minimum-size node cut-sets (implemented in all_node_cuts #1391).
    [#1415] Added fast approximation for k_components to the networkx.approximation package. This is based on White and Newman approximation algorithm for finding node independent paths between two nodes (see #1405).

Removed functionalities

    [#1236] The legacy ford_fulkerson maximum flow function is removed. Use edmonds_karp instead.

Miscellaneous changes

    [#1192] Support for Python 2.6 is dropped.

API Changes
Returning dictionaries

Several of the algorithms and the degree() method now return dictionaries keyed
by node instead of lists. In some cases there was a with_labels keyword which is
no longer necessary. For example,

>>> G=nx.Graph()
>>> G.add_edge('a','b')
>>> G.degree() # returns dictionary of degree keyed by node
{'a': 1, 'b': 1}

Asking for the degree of a single node still returns a single number

>>> G.degree('a')
1

The following now return dictionaries by default (instead of lists) and the
with_labels keyword has been removed:

        * Graph.degree(), MultiGraph.degree(), DiGraph.degree(),
DiGraph.in_degree(), DiGraph.out_degree(), MultiDiGraph.degree(),
MultiDiGraph.in_degree(), MultiDiGraph.out_degree().
        * clustering(), triangles()
        * node_clique_number(), number_of_cliques(), cliques_containing_node()
        * eccentricity()

The following now return dictionaries by default (instead of lists)

        * pagerank()
        * hits()

Adding nodes

add_nodes_from now accepts (node,attrdict) two-tuples

>>> G=nx.Graph()
>>> G.add_nodes_from([(1,{'color':'red'})])

Examples

        * Mayvi2 drawing
        * Blockmodel
        * Sampson?s monastery
        * Ego graph

Bug fixes

        * Support graph attributes with union, intersection, and other graph
operations
        * Improve subgraph speed (and related algorithms such as
connected_components_subgraphs())
        * Handle multigraphs in more operators (e.g. union)
        * Handle double-quoted labels with pydot
        * Normalize betweeness_centrality for undirected graphs correctly
        * Normalize eigenvector_centrality by l2 norm
        * read_gml() now returns multigraphs
