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

79877a9917 * take advantage of new possibilies in LLT (mat -= product) 
* fix Block::operator+= product which was not optimized
* fix some compilation issues

92a35c93b2 * extended the cache friendly products to support C = alpha * A * M and C += alpha * A * B 
* this allows to optimize xpr like C -= lazy_product, still have to catch "scalar_product_of_lazy_product"
* started to support conjugate in cache friendly products (very useful to evaluate A * B.adjoint() without
  evaluating B.adjoint() into a temporary
* compilation fix

544888e342 add a generic mechanism to copy a special matrix to a dense matrix so that 
we don't need to add other specialization of MatrixBase::operator=, Matrix::=,
and Matrix::Matrix(...)

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.)

2de9b7f537 fully vectorize DiagonalProduct 
(it used to be partially vectorized and that had been lost in the big changes from the previous commit)

a44f7cf440 re-enable the fast unaligned loads for gcc and icc using inline assembly 
(this allows to avoid incompatible pointer casts and to specify the dependency to the data explicitely)

6530c8f5b4 A much simplified version of the earlier commit introducing way fewer changes compared to changeset f292d2352e 
.
The reason of the previous commit was incorrect. The smart pointers issues were actually a result of issue 9.

71e5cbcbc4 Added specializations for DontAlign when using Dynamic matrices. 
This allows users to store Matrices in smart pointers without the
need for a specialized allocator/de-allocator.

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