a316cd8a76 now cmake takes snippets of code, completes them into compilable sources, builds them, 
executes them and stores their output in files.

a52c74095f rename src/ to Eigen/ so that we're able to #include<Eigen/Core.h> 
in the examples instead of ugly things like #include"../../src/Core.h"

04502cccd9 rename Block to DynBlock and rework API to make place for 
upcoming fixed-size Block matrix. Also some cleanup.

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

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__

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.

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
