4ca89f32ed Sparse matrix insertion: 
- automatically turn a SparseMatrix to uncompressed mode when calling insert(i,j).
 - now coeffRef insert a new element when it does not already exist

42e2578ef9 the min/max macros to detect unprotected min/max were undefined by some std header, 
so let's declare them after and do the respective fixes ;)

7bc8e3ac09 Initial fixes for bug #85. 
Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.
Changed boolean type 'ret' member to 'value'.
Changed 'ret' members refering to types to 'type'.
Adapted all code occurences.

2840ac7e94 big huge changes, so i dont remember everything. 
* 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

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.

0f15a8d829 QR: add isInjective(), isSurjective(), 
mark isFullRank() deprecated,
    add solve() (mix of Keir's patch and LU::solve())
=> there is big problem with complex which are not working

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

5015e48361 Sparse module: add a more flexible SparseMatrix::fillrand() function 
which allows to fill a matrix with random inner coordinates (makes sense
only when a very few coeffs are inserted per col/row)

86ccd99d8d Several improvements in sparse module: 
* 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.
