Minor improvement. Exception messages for matrix dimensions now tell you the values (in addition to a mere 'dimensions must match' we had before).

[Matrix] LeftMultiply with vector is exactly the same as TransposeThisAndMultiplty() with vector
Change LeftMultiply to a protected method (from protected abstract) and it now
calls TransposeThisAndMultiply(). TransposeThisAndMultiply has unit tests
so it was chosen as the "main" method. Overrides of LeftMultiply were removed,
because now only TransposeThisAndMultiply() needs to be overriden.

made parallel code serial code where it modifies a matrix, since we cannot guarantee subclasses are thread safe - in some cases making them thread safe hurts performance
