Eigen 3.2.7

   Released on November 5, 2015

   Changes since 3.2.6:
     * Main fixes and improvements:
          + Add support for dense.cwiseProduct(sparse).
          + Fix a regression regarding (dense*sparse).diagonal().
          + Make the IterativeLinearSolvers module compatible with
            MPL2-only mode by defaulting to COLAMDOrdering and
            NaturalOrdering for ILUT and ILLT respectively.
          + [59]Bug 266: backport support for c++11 move semantic
          + operator/=(Scalar) now performs a true division (instead of
            mat*(1/s))
          + Improve numerical accuracy in LLT and triangular solve by
            using true scalar divisions (instead of mat * (1/s))
          + [60]Bug 1092: fix iterative solver constructors for
            expressions as input
          + [61]Bug 1088: fix setIdenity for non-compressed sparse-matrix

     * Others:

            operations. This avoids real to complex conversions, and also
            fixes a compilation issue with MSVC.
          + Use explicit Scalar types for AngleAxis initialization
          + Fix several shortcomings in cost computation (avoid multiple
            re-evaluation in some very rare cases).
          + [63]Bug 1090: fix a shortcoming in redux logic for which
            slice-vectorization plus unrolling might happen.
          + Fix compilation issue with MSVC by backporting
            DenseStorage::operator= from devel branch.
          + [64]Bug 1063: fix nesting of unsupported/AutoDiffScalar to
            prevent dead references when computing second-order
            derivatives
          + [65]Bug 1100: remove explicit CMAKE_INSTALL_PREFIX prefix to
            conform to cmake install's DESTINATION parameter.
          + unsupported/ArpackSupport is now properly installed by make
            install.
          + [66]Bug 1080: warning fixes
