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

1d52bd4cad the big memory changes. the most important changes are: 
ei_aligned_malloc now really behaves like a malloc
 (untyped, doesn't call ctor)
ei_aligned_new is the typed variant calling ctor
EIGEN_MAKE_ALIGNED_OPERATOR_NEW now takes the class name as parameter

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 ?

d9e5fd393a * In LU solvers: no need anymore to use row-major matrices 
* Matrix: always inherit WithAlignedOperatorNew, regardless of
vectorization or not
* rename ei_alloc_stack to ei_aligned_stack_alloc
* mixingtypes test: disable vectorization as SSE intrinsics don't allow
mixing types and we just get compile errors there.
