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 :)

96524fc573 Split Row and Column into separate files. 
Introduce a notion of RowVector (typedef for Matriw with 1 row)
Make row() return a row vector instead of a "column vector"
Introduce operator[] to access elements of row/column vectors uniformly
Remove default arguments in operator(), these were for vectors, now use operator[] instead

2d823d8ef6 Generic loop unrolling with template metaprograms. It seems to be as fast as 
manually unrolling.
TODO: decide when to stop unrolling (speed vs. code size).
      maybe only unroll one loop for larger matixes.

1d3743d2c5 for dynamic size matrix (Rows|Cols)AtCompileTime is always EiDynamic and not 
"(Rows|Cols)AtCompileTime - 1" which would be EiDynamic - 1 == -2

4241dddee9 temporarily remove division unit-tests. they caused div-by-zero's , reported by Michael Olbrich. 
The solution will consist in adding a real Traits system.

5160e9d029 Half-way commit prefixing object names. I am forced to commit now 
because I renamed a file once with a wrong filename and svn refuses to
let me rename it again, tells me i should propagate first.

4e299afb1f don't enclose eigen in a namespace. prefixing is the way to go. 
For example Qt uses a prefix and no namespace (except for a few things)

628b1a8f6d implement scalar operators separately for each type using a macro. 
This is required e.g. to allow "2 * m" with m a matrix of doubles.
