c3bab0edb7 fix #12, but the fix is not optimal, householder transformations need to be rethought in the complex case, see:

9e00d94543 * the Upper->UpperTriangular change
* finally get ei_add_test right

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...

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some
still fail at runtime in ei_aligned_free() (even without vectorization).

55aeb1f83a Optimizations:
* faster matrix-matrix and matrix-vector products (especially for not aligned cases)
 * faster tridiagonalization (make it using our matrix-vector impl.)
Others:
 * fix Flags of Map
 * split the test_product to two smaller ones

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.

0ee6b08128 * split Product to a DiagonalProduct template specialization
to optimize matrix-diag and diag-matrix products without
  making Product over complicated.
* compilation fixes in Tridiagonalization and HessenbergDecomposition
  in the case of 2x2 matrices.
* added an Orientation2D small class with similar interface than Quaternion
  (used by Transform to handle 2D and 3D orientations seamlessly)
* added a couple of features in Transform.

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.

e3fac69f19 Added a Hessenberg decomposition class for both real and complex matrices.
This is the first step towards a non-selfadjoint eigen solver.
Notes:
 - We might consider merging Tridiagonalization and Hessenberg toghether ?
 - Or we could factorize some code into a Householder class (could also be shared with QR)

4dd57b585d * rewrite of the QR decomposition:
- works for complex
  - allows direct access to the matrix R
* removed the scale by the matrix dimensions in MatrixBase::isMuchSmallerThan(scalar)

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

(see notes in Core/util/StaticAssert.h for details)

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

06752b2b77 * added a Tridiagonalization class for selfadjoint matrices
* added MatrixBase::real()
* added the ability to extract a selfadjoint matrix from the
  lower or upper part of a matrix, e.g.:
    m.extract<Upper|SelfAdjoint>()
  will ignore the strict lower part and return a selfadjoint.
  This is compatible with ZeroDiag and UnitDiag.
