BUG: By default, do not create any fixed parameters.

A transform does not usually have the same number of FixedParameters as
Parameters -- it commonly does not have any FixedParameters at all.

Make the default number of FixedParameters in the itk::Transform constructor
to be zero.

STYLE: Remove trivial method comments in itkTransform.hxx.

These add clutter create doxygen ambiguities. Also remove some old commented
out code.
