78ba523d30 Make snippet run successfully again: 
the snippet for 'eval' was taking m=m.transpose() as an example of code
 that needs an explicit call to eval(), but that doesn't work anymore now
 that we have the clever assert detecting aliasing issues.

2840ac7e94 big huge changes, so i dont remember everything. 
* 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
