big reorganisation of asserts, so that:
...
0) asserts are only done in the public API, except for a few ones explicitly
named eigen_internal_assert.
1) internal asserts are disabled unless EIGEN_INTERNAL_DEBUGGING is defined.
This limits the impact of debugging on performance.
2) no 'unused argument' warnings anymore when compiling with -DNDEBUG

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.

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.

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

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 :)
