*	big huge changes, so i dont remember everything.	Benoit Jacob	2009-10-28
\| \| \| \| \| \| \| \| \| \|	* renaming, e.g. LU ---> FullPivLU * split tests framework: more robust, e.g. dont generate empty tests if a number is skipped * make all remaining tests use that splitting, as needed. * Fix 4x4 inversion (see stable branch) * Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices. * CMakeLists: more robust regexp to parse the version number * misc fixes in unit tests
*	add a SparseNestByValue expression and fix issue in sparse adjoint evaluation	Gael Guennebaud	2009-07-13
\|
*	remove sentence "Eigen itself is part of the KDE project."	Benoit Jacob	2009-05-22
\| \| \| \|	it never made very precise sense. but now does it still make any?
*	new simplified API to fill sparse matrices (the old functions are	Gael Guennebaud	2009-05-04
\| \| \| \| \| \| \| \| \| \| \| \|	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.
*	- add diagonal * sparse product as an expression	Gael Guennebaud	2009-02-09
\| \| \| \| \|	- split sparse_basic unit test - various fixes in sparse module
*	QR: add isInjective(), isSurjective(),	Gael Guennebaud	2009-01-28
\| \| \| \| \| \|	mark isFullRank() deprecated, add solve() (mix of Keir's patch and LU::solve()) => there is big problem with complex which are not working
*	add support for read/write sub sets of inner vectors (sparse module)	Gael Guennebaud	2009-01-27
\|
*	sparse module: makes -= and += operator working	Gael Guennebaud	2009-01-23
\| \| \| \| \| \|	Question 1: why are *=scalar and /=scalar working right away ? Same weirdness in DynamicSparseMatrix where operators += and -= work wihout having to redefine them ???
*	fix a few remaining warnings	Gael Guennebaud	2009-01-23
\| \| \| \|	and fix commainitializer unit test with MSVC
*	* fix compilation with gcc 3.4	Gael Guennebaud	2009-01-23
\| \| \| \|	* add an option to disable Qt testing
*	sparse module:	Gael Guennebaud	2009-01-21
\| \| \| \| \|	* add row(i), col(i) functions * add prune() function to remove small coefficients
*	add a flexible sparse matrix class designed for fast matrix assembly	Gael Guennebaud	2009-01-19
\|
*	Sparse module: add support for sparse selfadjoint * dense	Gael Guennebaud	2009-01-15
\|
*	Sparse module: add row/col methods to the iterators	Gael Guennebaud	2009-01-15
\|
*	Sparse module: bugfix in SparseMatrix::resize(), now the indices are	Gael Guennebaud	2009-01-15
\| \| \| \|	correctly initialized to 0.
*	Sparse module:	Gael Guennebaud	2009-01-14
\| \| \| \| \|	* improved performance of mat=scalar bug fix in cwise*
*	Add support for sparse * dense and dense * sparse matrix/vector products	Gael Guennebaud	2009-01-14
\|
*	Big rewrite in the Sparse module: SparseMatrixBase no longer inherits ↵	Gael Guennebaud	2009-01-14
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	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
*	Sparse module: add a more flexible SparseMatrix::fillrand() function	Gael Guennebaud	2008-12-11
\| \| \| \| \|	which allows to fill a matrix with random inner coordinates (makes sense only when a very few coeffs are inserted per col/row)
*	Several improvements in sparse module:	Gael Guennebaud	2008-11-05
	* add a LDL^T factorization with solver using code from T. Davis's LDL library (LPGL2.1+) * various bug fixes in trianfular solver, matrix product, etc. * improve cmake files for the supported libraries * split the sparse unit test * etc.
