(maint) Change parameter names and cleanup

This work udpates the parameter names for less typing and overall
cleaner code.  There are some README udpates to give a bit more
information as well as some fixes of some unused code.

Note, you may have to update your parameter names, though most of the
param names were internal and most likely would not need overwriting.
