884a718b0a make shameless use of const_cast to reduce code redundancy. This means Eigen2
gives up enforcing constness. I really tried to enforce it, but it really was
much hassle because our expression templates can be lvalues (not only rvalues)
and so much code had to be written twice.

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.

a94a8c68e8 add fromArray() and wrapArray().
For example, the following now works:

  double a1[3] = {1.0, 3.0, 2.0}, a2[3];
  Vector3d::wrapArray(a2) = 2 * Vector3d::fromArray(a1);
  cout << Vector3d::fromArray(a2) << endl; // output: 2,6,4

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.

After huge thread on eigen mailing list, it appears that i'm the
only one in favor of prefix Ei. Everybody else prefers namespace
Eigen like we did in Eigen 1. So, revert.

Also add a macro USING_EIGEN_DATA_TYPES that application programmers
can use to automatically do "using"on the Matrix class and its
matrix/vector typedefs:
using Eigen::Matrix;
using Eigen::Matrix2d;
using Eigen::Vector2d;
... (the list of typedefs is really long).

thanks to the suffixes, the Vector typedefs aren't really polluting.

P.S. Danny, please skip this one :) I know you already reported the
namespace->prefix move, now that one would be too much noise :)
