  Fix some mistakes in documentation

Note that one cannot use arbitrary section headings in numpydoc.  For
instance, the section headings "Usage", "Keywords", and
"Return Values" are not valid section headings, and would give warnings
when building documentation.

In addition, the routine matlab.tfdata was documented incorrectly (the
documentated behavior did not match the actual behavior when keyword
arguments were used).

Fix #45 - make gain vector optional in root_locus

Checked and this looks OK.  For posterity, what was the reason for getting rid of some of the **kw arguments:

    -def tfdata(sys, **kw):
    +def tfdata(sys):
