789ea9d676 unless i find more failures in the tests, this will be beta3... 
* fixes for mistakes (especially in the cast() methods in Geometry) revealed by the new "mixing types" test
* dox love, including a section on coeff access in core and an overview in geometry

89f468671d * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/ 
* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated"
warning which I haven't looked much into

582c1f92c8 doc: add a "non stable" warning for parts which are not part 
of the stable API yet and a couple of other minor doc updates...

139529e97b * add .imag() function 
* fix a very old bug in EigenSolver that I had completely forgotten
  (thanks to Timothy to refresh my mind)
* fix doc of Matrix::Map

1fc503e3ce add EigenSolver::eigenvectors() method for non symmetric matrices. 
However, for matrices larger than 5, it seems there is constantly a quite large error for a very
few coefficients. I don't what's going on, but that's certainely not due to numerical issues only.
(also note that the test with the pseudo eigenvectors fails the same way)

d907cd4410 Fixes in Eigensolver: 
* eigenvectors => pseudoEigenvectors
 * added pseudoEigenvalueMatrix
 * clear the documentation
 * added respective unit test
Still missing: a proper eigenvectors() function.

172000aaeb Add .perpendicular() function in Geometry module (adapted from Eigen1) 
Documentation:
 * add an overview for each module.
 * add an example for .all() and Cwise::operator<

6f09d3a67d - many updates after Cwise change 
- fix compilation in product.cpp with std::complex
- fix bug in MatrixBase::operator!=

4af7089ab8 * Added a generalized eigen solver for the selfadjoint case. 
(as new members to SelfAdjointEigenSolver)
  The QR module now depends on Cholesky.
* Fix Transpose to correctly preserve the *TriangularBit.

001b01a290 Rewrite from scratch of the eigen solver for symmetric matrices 
which now supports selfadjoint matrix. The implementation follows
Golub's famous book.

559233c73e * fix the QR module to use extract/part instead of the previous triangular stuff 
* added qr and eigensolver tests
* fix a compilation warning in Matrix copy constructor

fd2e9e5c3c * Clean a bit the eigenvalue solver: if the matrix is known to be 
selfadjoint at compile time, then it returns real eigenvalues.
* Fix a couple of bugs with the new product.

45cda6704a * Draft of a eigenvalues solver 
(does not support complex and does not re-use the QR decomposition)

* Rewrite the cache friendly product to have only one instance per scalar type !
  This significantly speeds up compilation time and reduces executable size.
  The current drawback is that some trivial expressions might be
  evaluated like conjugate or negate.

* Renamed "cache optimal" to "cache friendly"

* Added the ability to directly access matrix data of some expressions via:
  - the stride()/_stride() methods
  - DirectAccessBit flag (replace ReferencableBit)
