From 721626dfc5cab61ded1a26357b6c3dbb33763dc0 Mon Sep 17 00:00:00 2001

Subject: * 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.
