* Eigen compiles with any GCC versions from, at least, 3.3 without the previous ugly hack :)
...
* Renamed the scalar functors with the "Scalar" prefix (instead of "Cwise")

Patch by Gael Guennebaud:
...
Rework the matrix storage to ensure optimal sizeof in all cases, while
keeping the decoupling of matrix sizes versus storage sizes.
Also fixing (recently introduced) bugs caused by unwanted
reallocations of the buffers.

alpha 3.1. in this commit:
...
- finally get the Eval stuff right. get back to having Eval as
a subclass of Matrix with limited functionality, and then,
add a typedef MatrixType to get the actual matrix type.
- add swap(), findBiggestCoeff()
- bugfix by Ramon in Transpose
- new demo: doc/echelon.cpp

Eval is now implemented like the other expression types, it no longer
...
inherits Matrix. Remove the typedefs I added in Matrix.

cleanup in Eval; instead introduce convenient typedefs in Matrix
...
for naming special related matrix types: RowType, ColumnType,
BlockType

big architecture change dissociating "actual" dimensions from "maximum possible"
...
dimension. The advantage is that evaluating a dynamic-sized block in a fixed-size
matrix no longer causes a dynamic memory allocation. Other new thing:
IntAtRunTimeIfDynamic allows storing an integer at zero cost if it is known at
compile time.

-add set...() methods and their documentation; remove Generic
...
-use row-major traversal when the number of columns is fixed
and the number of rows is dynamic

revert most of previous commit. It really is better to forbid default
...
constructor for dynamic-size matrices. Now why do I feel like a beheaded
chicken running around?

Revert to allowing default Matrix constructor even for dynamic size (which is
...
then set to 1). Discussion with jonasp made me remember why we did so in Eigen1.
Also add default constructor to Eval

remove all the _Order mechanics, now we are always traversing matrices in
...
column-major order, even if storage is row-major. Benchmark showed that adapting
the traversal order to the storage order brought no benefit.
Also do some cleanup after Gael's big patch.
