Removes unused, un-documented code

A large chunk of code used once upon a time to
report SDQA values is removed.  There must be
a better mechanism for doing this now.
Updates docstrings

In places docstrings were out of date.
In others the docstrings were not in standard format.
This commit fixes up the docstrings.
Fixes formatting issues of docstrings

Apparently Doxygen doesn't like colons, so I removed them.
I also fixed a typo afw.algorithms -> meas.algorithms.
Removes test using removed code.

There was a unit test for the Sdqa code removed as part of this
ticket.  This commit removes that unit test.
