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.

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 :)

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.

ee63e15e2c make matrix multiplication do immediate evaluation; add lazyMul() for the old behaviour
some reorganization, especially in MatrixStorage
start playing with loop unrolling, always_inline, and __restrict__

835e0c9f67 Found a way to have eval() be a member function of class EiObject, instead of a global function.

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)

55227b1f63 Deep refactoring.
1) Kill MatrixXpr class, instead let all class inherit a common EigenBase class
2) Kill MatrixBase/Matrix/Vector classes, instead introduce a single Matrix class,
a MatrixStorage class, and typedefs to emulate vectors
3) Huge code cleanup, remove large preprocessor macros, sloccount drop to ~750
down from 1100.
4) Introduce compile-time-known sizes

1af61c6ff0 reorganize header files, split MatrixBase into smaller files.
expose only a few meta-headers to the user, the rest moves to a internal/ subdirectory

fe9b6b8f17 remove the MatrixConstXpr and MatrixConstRef classes.
Now the user doesn't need anymore to call .xpr() and can simply do:
matrix.row(i) += matrix.row(j)

Also remove the obsolete MatrixXpr::hasDynamicSize() method (thanks to
Michael Olbrich for reporting this).
