1b257a7620 add an optimized "apply in place a rotation in the plane", 
and make Jacobi and SelfAdjointEigenSolver use it
=> ~ x1.75 speedup for JacobiSVD and x2 for SelfAdjointEigenSolver

1578421ed1 fix issue #25 : the problem was that we assumed Dynamic was a multiple of a packet size 
(also disable the test of blueNorm)

a2087cd7a3 Add an efficient rank2 update function (like the level2 blas xSYR2 routine). 
Note that it is already used in Tridiagonalization.

ea23f36c78 * change the nesting order of adjoint_return_type to 
1 - make it easier to catch conjugate expressions
 2 - make sure there is no unecessary copy (we had NestByValue<Derived> which seems to be very bad)
* update eigensolver wrt recent changes

1aea45335f * bybye Part, welcome TriangularView and SelfAdjointView. 
* move solveTriangular*() to TriangularView::solve*()
* move .llt() to SelfAdjointView
* add a high level wrapper to the efficient selfadjoint * vector product
* improve LLT so that we can specify which triangular part is meaningless
=> there are still many things to do (doc, cleaning, improve the matrix products, etc.)

e093b43b2c * rename QR to HouseholderQR because really that impacts the API, not just the impl. 
* rename qr() to householderQr(), for same reason.
* clarify that it's non-pivoting, non-rank-revealing, so remove all the rank API, make solve() be void instead of bool, update the docs/test, etc.
* fix warning in SVD

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

0523b64fe9 Eigensolver decomposition interface unification. 
Added default ctor and public compute method as
well as safe-guards against uninitialized usage.
Added unit tests for the safe-guards.

70c0174bf9 * allows fixed size matrix with size==0 (via a specialization of 
MatrixStorage returning a null pointer). For instance this is very
  useful to make Tridiagonalization compile for 1x1 matrices
* fix LLT and eigensolver for 1x1 matrix
