Renamed PlainMatrixType to PlainObject (Array != Matrix).
...
Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).

introduce ei_xxx_return_value and ei_xxx_impl for xxx in solve,kernel,impl
...
put them in a new internal 'misc' directory

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

kill ei_add_test_multi. Now the macro ei_add_test does all that automatically, by parsing the source file. No risk anymore to specify the wrong number of tests! Also, introduce CALL_SUBTESTX for X=1..10 that allows to port existing code much quicker. And port already the product* and eigensolver* files.

Add new default option EIGEN_SPLIT_LARGE_TESTS and cmake macro ei_add_test_multi.
...
When enabled, large tests are split into smaller executables.
This needs minimal changes in the unit tests.
Updated the LU test to use it.

remove the m_originalMatrix member. Instead, image() now takes the original matrix as parameter. It was the only method to use it anyway. Introduce m_isInitialized.

big huge changes in LU!
...
* continue the decomposition until a pivot is exactly zero;
don't try to compute the rank in the decomposition itself.
* Instead, methods such as rank() use a new internal parameter
called 'threshold' to determine which pivots are to be
considered nonzero.
* The threshold is by default determined by defaultThreshold()
but the user can override that by calling useThreshold(value).
* In solve/kernel/image, don't assume that the diagonal of U
is sorted in decreasing order, because that's only approximately
true. Additional work was needed to extract the right pivots.

move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>.
...
also: adding resize() to MatrixBase was really needed ;)

* make LU::kernel() and LU::image() also use ReturnByValue
...
* make them return zero vector in the degenerate case, instead of asserting
(let's stick to the principle that we only assert on memory errors)

Added default ctor and public compute method as well
as safe-guards against uninitialized usage.
Added unit tests for the safe-guards.

if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with
...
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.

with almost zero failures.

* bugfix in SolveTriangular found by Timothy Hunter (did not compiled for 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...
