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.

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

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).
