247f2b0ffa * block() for vectors ---> segment() 
* documentation improvements, especially in quickstart guide

2120fed849 * bug fixes in: Dot, generalized eigen problem, singular matrix detetection in Cholesky 
* fix all numerical instabilies in the unit tests, now all tests can be run 2000 times
  with almost zero failures.

9466e5f94e * doc improvements in Cwise and PartialRedux: 
- 33 new snippets
  - unfuck doxygen output in Cwise (issues with function macros)
  - more see-also links from outside, making Cwise more discoverable
* rename matrixNorm() to operatorNorm(). There are many matrix norms
  (the L2 is another one) but only one is called the operator norm.
  Risk of confusion with keyword operator is not too scary after all.

842c4f8bfa Several compilation fixes for MSVC and NVCC, basically: 
- added explicit enum to int conversion where needed
- if a function is not defined as declared and the return type is "tricky"
  then the type must be typedefined somewhere. A "tricky return type" can be:
  * a template class with a default parameter which depends on another template parameter
  * a nested template class, or type of a nested template class

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<

c10f069b6b * Merge Extract and Part to the Part expression. 
Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
  first letter: Identity, Zero, Ones and Random.

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.

f07f907810 Add QR and Cholesky module instantiations in the lib. 
To try it with the unit tests set the cmake variable TEST_LIB to ON.

2126baf9dc add an optimized path for the tridiagonalization of a 3x3 matrix. 
(useful for plane fitting, and covariance analysis of 3D data)

366971bea4 * start of the Geometry module with a cross product and quaternion expressions 
(haven't tried them yet)
* applied the meta selector rule to MatrixBase::swap()

75de41a00b big changes in Doxygen configuration; work around bug with doxygen parsing of 
initialized enum values showing the last word the initializer instead of the actual
enum value's name; add some more docs.

54ae2ac7e8 Added the computation of eigen vectors in the symmetric eigen solver. 
However the eigen vectors are not correct yet, but I really cannot find the
problem.

3b0523041a since m*m.adjoint() is positive, so are its eigenvalues, so no need for 
cwiseAbs()

0444e3601a - add MatrixBase::eigenvalues() convenience method 
- add MatrixBase::matrixNorm(); in the non-selfadjoint case, we reduce to the
  selfadjoint case by using the "C*-identity" a.k.a.
	norm of x = sqrt(norm of x * x.adjoint())

92b7e2d6a1 fix a couple of issues making the eigensolver test compile and run without aborting 
on an assert. Had to fix a stupid bug in Block -- very strange we hadn't hit it
before.

However the test still fails.

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