Initial import of eigen 2.0beta5

Eigen 2 is a C++ template library for linear algebra: vectors, matrices, and
related algorithms. It is:
* Versatile. Eigen handles, without code duplication, and in a completely
  integrated way:
  o both fixed-size and dynamic-size matrices and vectors.
  o both dense and sparse (the latter is still experimental) matrices and
    vectors.
  o both plain matrices/vectors and abstract expressions.
  o both column-major (the default) and row-major matrix storage.
  o both basic matrix/vector manipulation and many more advanced, specialized
    modules providing algorithms for linear algebra, geometry, quaternions,
    or advanced array manipulation.
* Fast.
  o Expression templates allow to intelligently remove temporaries and enable
    lazy evaluation, when that is appropriate -- Eigen takes care of this
    automatically and handles aliasing too in most cases.
  o Explicit vectorization is performed for the SSE (2 and later) and AltiVec
    instruction sets, with graceful fallback to non-vectorized code.
    Expression templates allow to perform these optimizations globally for
    whole expressions.
  o With fixed-size objects, dynamic memory allocation is avoided, and the
    loops are unrolled when that makes sense.
  o For large matrices, special attention is paid to cache-friendliness.
* Elegant. The API is extremely clean and expressive, thanks to expression
  templates. Implementing an algorithm on top of Eigen feels like just copying
  pseudocode. You can use complex expressions and still rely on Eigen to
  produce optimized code: there is no need for you to manually decompose
  expressions into small steps.
* Compiler-friendy. Eigen has very reasonable compilation times at least with
  GCC, compared to other C++ libraries based on expression templates and heavy
  metaprogramming. Eigen is also standard C++ and supports various compilers.
