Seal ConjugateTranspose() for double/single and remove redundant overrides
For non-complex matrices, the ConjugateTranspose is the same
as the transpose. Therefore, a sealed override for
ConjugateTranspose() that simply forwards the call to Transpose()
makes sense for double/single matrices.

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.
