* change block selection threshold from 1e-2 to 1e-1
* add rigorous precision test

* 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 computeInverseWithCheck
* doc improvements
* update test

in particular, the API is essentially finalized and the 4x4 case is fixed to be numerically stable.

(result undefined, but at least it won't take forever on intel 387)
* add lots of comments, especially to LU.h
* fix stuff I had broken in Inverse.h
* split inverse test

coding style
* add snippet for computeInverseWithCheck documentation
* expand unit-tests to cover computeInverseWithCheck

it never made very precise sense. but now does it still make any?

few bits left of the comma and for floating-point types will never return zero.
This replaces the custom functions in test/main.h, so one does not anymore need
to think about that when writing tests.

* fix all numerical instabilies in the unit tests, now all tests can be run 2000 times
with almost zero failures.

very small fixed size matrices)
* bugfix in Dot unroller
* added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude
this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...

make use of static asserts in Map
fix 2 warnings in CacheFriendlyProduct: unused var 'Vectorized'
|

Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
first letter: Identity, Zero, Ones and Random.

- remove all invertibility checking, will be redundant with LU
- general case: adapt to matrix storage order for better perf
- size 4 case: handle corner cases without falling back to gen case.
- rationalize with selectors instead of compile time if
- add C-style computeInverse()
* update inverse test.
* in snippets, default cout precision to 3 decimal places
* add some cmake module from kdelibs to support btl with cmake 2.4

discovered that m1 == m1.inverse().inverse() fails though
m1.inverse()*m1 == I
