ff6a46105d * Refactoring of the class hierarchy: introduction of DenseDirectAccessBase, removal of extra _Base/_Options template parameters. 
* Introduction of strides-at-compile-time so for example the optimized code really knows when it needs to evaluate to a temporary
* StorageKind / XprKind
* Quaternion::setFromTwoVectors: use JacobiSVD instead of SVD
* ComplexSchur: support the 1x1 case

871698d3aa Introduced NestParentByRefBit and NestByRefBit - this should fix temporaries related to nested products. 
Fixed a few typos and a few warnings.

1e62e0b0d8 more ET refactoring: 
* extend Cwise for multiple storage base class

2a3a6fe45e Experiment the ET refactoring on Transpose for Dense and Sparse storages. 
All tests work fine.

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

2829314284 new simplified API to fill sparse matrices (the old functions are 
deprecated). Basically there are now only 2 functions to set a
coefficient:
1) mat.coeffRef(row,col) = value;
2) mat.insert(row,col) = value;
coeffRef has no limitation, insert assumes the coeff has not already
been set, and raises an assert otherwise.
In addition I added a much lower level, but more efficient filling
mechanism for
internal use only.

e7c48fac9b sparse module: makes -= and += operator working 
Question 1: why are *=scalar and /=scalar working right away ?
Same weirdness in DynamicSparseMatrix where operators += and -= work wihout
  having to redefine them ???

c4c70669d1 Big rewrite in the Sparse module: SparseMatrixBase no longer inherits MatrixBase. 
That means a lot of features which were available for sparse matrices
via the dense (and super slow) implemention are no longer available.
All features which make sense for sparse matrices (aka can be implemented efficiently) will be
implemented soon, but don't expect to see an API as rich as for the dense path.
Other changes:
* no block(), row(), col() anymore.
* instead use .innerVector() to get a col or row vector of a matrix.
* .segment(), start(), end() will be back soon, not sure for block()
* faster cwise product

709e903335 Sparse module: 
* extend unit tests
* add support for generic sum reduction and dot product
* optimize the cwise()* : this is a special case of CwiseBinaryOp where
  we only have to process the coeffs which are not null for *both* matrices.
  Perhaps there exist some other binary operations like that ?
