5adcc6c7b4 Add support for NVCC5: most of the Core and part of LU are callable from CUDA code.
Still a lot to do.

a76fbbf397 Fix bug #314:
- remove most of the metaprogramming kung fu in MathFunctions.h (only keep functions that differs from the std)
- remove the overloads for array expression that were in the std namespace

fe85b7ebc6 fix several const qualifier issues: double ones, meaningless ones, some missing ones, etc.
(note that const qualifiers are set by internall::nested)

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.

ab2b33e802 Add cast to aliasing check.
Otherwise, one of the geo tests fails to compile. Now there are some compiler
warnings about aliasing and type-punned pointers that I don't understand.

e54faba198 merge the backing-out of the stupid RetByVal change, and implement a simple

641d968a9a * Make ReturnByValue have the EvalBeforeAssigningBit and explicitly
enforce this mechanism (otherwise ReturnByValue bypasses it).
 (use .noalias() to get the old behavior.)
* Remove a hack in Inverse, futile optimization for 2x2 expressions.

e277586958 Complete rework of global math functions and NumTraits.
* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.

d02eccf584 add SSE path for Matrix4f inverse, taken from Intel except that we do a kosher
division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is
that elsewhere in Eigen we dont allow ourselves this approximation (which throws
2 bits of mantissa), so there's no reason we should allow it here.

832045d363 Warning 4512 (assignment operators could not be generated) is now simply disabled.
All unimplemented assignment operators have been removed.

d2e44f2636 * 4x4 inverse: revert to cofactors method
* inverse tests: use createRandomMatrixOfRank, use more strict precision
* tests: createRandomMatrixOfRank: support 1x1 matrices
* determinant: nest the xpr
* Minor: add comment

44d0d667cd 4x4 inverse:
* change block selection threshold from 1e-2 to 1e-1
* add rigorous precision test

e3d890bc5a Another big refactoring change:
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix

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

ec02388a5d big rewrite in Inverse.h
in particular, the API is essentially finalized and the 4x4 case is fixed to be numerically stable.

13f31b8daf * make PartialLU avoid to generate inf/nan when given a singular matrix
(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

e82ab8a5dd move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>.
also: adding resize() to MatrixBase was really needed ;)

6347b1db5b remove sentence "Eigen itself is part of the KDE project."
it never made very precise sense. but now does it still make any?

7c14e1eac4 add partial-pivoting LU decomposition
the name 'PartialLU' is not meant to be definitive!
make inverse() and determinant() use it, so it's *almost* considered
well tested.

fabaa6915b * fix in IO.h, a useless copy was made because of assignment from
Derived to MatrixBase.
* the optimization of eval() for Matrix now consists in a partial
  specialization of ei_eval, which returns a reference type for Matrix.
  No overriding of eval() in Matrix anymore. Consequence: careful,
  ei_eval is no longer guaranteed to give a plain matrix type!
  For that, use ei_plain_matrix_type, or the PlainMatrixType typedef.
* so lots of changes to adapt to that everywhere. Hope this doesn't
  break (too much) MSVC compilation.
* add code examples for the new image() stuff.
* lower a bit the precision for floats in the unit tests as
  we were already doing some workarounds in inverse.cpp and we got some
  failed tests.

c1e2156d8a * Much better, consistent error msgs when mixing different scalar types:
- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
  ops to take two different scalar types. The functors that we defined take two args
  of the same type anyway; also we still allow the return type to be different.
  Again the reason is that different scalar types are incompatible with vectorization.
  Better have the user realize explicitly what mixing different numeric types costs him
  in terms of performance.
  See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts
