db030d4e28 * fix issues with "long double" type (useful to enforce the use of x87 registers) 
* extend the documentation on "extending Eigen"

46fe7a3d9e 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.

f0394edfa7 * 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...

baf0cffedd *add operator()(int) for vectors, synonymous to operator[](int). 
I don't see any reason not to allow it, it doesn't add much code, and
 it makes porting from eigen1 easier.
*expand tests/basicstuff to first test coefficient access methods

c10f069b6b * Merge Extract and Part to the Part expression. 
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.

8463b7d3f4 * fix compilation issue in Product 
* added some tests for product and swap
* overload .swap() for dynamic-sized matrix of same size

522e24f2d7 update of the testing framework: 
replaced the QTestLib framework my custom macros
and a (optional) custom script to run the tests from ctest.

f279162ec4 * introducte recursive Flags system for the expressions 
-- currently 3 flags: RowMajor, Lazy and Large
 -- only RowMajor actually used for now
* many minor improvements

2ee68a074e generalized ei_traits<>. 
Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE
because it does not only import the ei_traits, it also makes the base class
a friend, etc.

f64311e07d Extended the comma initializer to support xpr on the right side: 
Matrix3i mat; Vector2i vec(33,66);
  mat << vec.transpose(), 99,
         vec, Matrix2i::random();

721626dfc5 * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4; 
If the number of coefficients does not match the matrix size, then an assertion is raised.
  No support for xpr on the right side for the moment.

* Added support for assertion checking. This allows to test that an assertion is indeed raised
  when it should be.

* Fixed a mistake in the CwiseUnary example.

8e0d548039 * Fix a compilation issue with large fixed-size matrices: the unrollers were always instanciated. 
* the unrolling limits are configurable at compile time.

6907886a15 prefix global functions with ei_ as previous solution was rather 
fragile. also fix compilation with g++ 4.3.

84934ea217 - move: DerivedTraits becomes MatrixBase::Traits 
- the static constants are private again in the Derived classes
- more documentation and code snippets
- new isDiagonal() method

dad245af56 - eigen2 now fully enforces constness! found a way to achieve that 
with minimal code duplication. There now are only two (2)
  const_cast remaining in the whole source code.
- eigen2 now fully allows copying a row-vector into a column-vector.
  added a unit-test for that.
- split unit tests, improve docs, various improvements.

f355ef2df0 Merge WrapArray into FromArray. Less code. The downside is that we're using one more 
const_cast. But I think that anyway trying to maintain const strictness in Eigen2 is not
worth the hassle.

Konstantin: so the code snippet I sent you won't work anymore, replace wrapArray with fromArray.

e445f5085a implement the first _real_ unit-tests, testing the results for correctness instead 
of just checking compilation.

Fix the many issues discovered by these unit-tests, by the way fixing a performance bug.
