* add some 1x1 tests
...
* temporarily disable tests that strangely fail, with a big FIXME

* 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

Introduce third template parameter to HouseholderSequence: int Side.
...
When it's OnTheRight, we read householder vectors as rows above the diagonal.
With unit test. The use case will be bidiagonalization.

* Fix a bug in HouseholderQR with mixed fixed/dynamic size: must use EIGEN_SIZE_MIN instead of EIGEN_ENUM_MIN, and there are many other occurences throughout Eigen!
...
* HouseholderSequence:
- add shift parameter
- add essentialVector() method to start abstracting the direction
- add unit test in householder.cpp

make applyHouseholderOnTheRight take a row vector, not a column vector:
...
this is how it's used in practice.

Big renaming:
...
start ---> head
end ---> tail
Much frustration with sed syntax. Need to learn perl some day.

*adapt Householder to the convention that we now favor refs over ptrs for output. Keep "workspace" as pointer because it is an array (which is now more obvious).
...
*rename makeHouseholderSequence to householderSequence, because that's what it returns.

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

* add a HouseholderSequence class (not good enough yet for Triadiagonalization and HessenbergDecomposition)
...
* rework a bit AnyMatrixBase, and mobe it to a separate file
