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

Michael was right, it's best to base the unrolling limit on the product Rows*Cols.

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.

make matrix multiplication do immediate evaluation; add lazyMul() for the old behaviour

start playing with loop unrolling, always_inline, and __restrict__

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.

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)

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
