Removed default parameter from Transform.
Removed the TransformXX typedefs.
Removed references to TransformXX from unit tests and docs.
Assigning Transforms to a sub-group is now forbidden at compile time.
Products should now properly support the Isometry flag.
Fixed alignment checks in MapBase.
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix
* replace implicit constructor AngleAxis(QuaternionBase&) by an explicit one, it seems ambiguous for the compiler
* remove explicit constructor with conversion type quaternion(Quaternion&): conflict between constructor.
* modify EIGEN_INHERIT_ASSIGNEMENT_OPERATORS to suit Quaternion class
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests
* extend PartialRedux::cross() to any matrix sizes with automatic
vectorization when possible
* unit tests: add "geo_" prefix to all unit tests related to the
geometry module and start splitting the big "geometry.cpp" tests to
multiple smaller ones (also include new tests)
