This module parses any CLI options that use a "shorthand"
syntax::
--foo A=b,C=d

Shorthand syntax
This module provides two main classes to do this.
First, there's a ``ShorthandParser`` class. This class works
on a purely syntactic level. It looks only at the string value
provided to it in order to figure out how the string should be parsed.
However, because there was a pre-existing shorthand parser, we need
to remain backwards compatible with the previous parser. One of the
things the previous parser did was use the associated JSON model to
control how the expression was parsed.
In order to accommodate this a post processing class is provided that
takes the parsed values from the ``ShorthandParser`` as well as the
corresponding JSON model for the CLI argument and makes any adjustments
necessary to maintain backwards compatibility. This is done in the
``BackCompatVisitor`` class.
