Gael Guennebaud 721626dfc5 * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4;
If the number of coefficients does not match the matrix size, then an assertion is raised.
  No support for xpr on the right side for the moment.

* Added support for assertion checking. This allows to test that an assertion is indeed raised
  when it should be.

* Fixed a mistake in the CwiseUnary example.
