<#
.DESCRIPTION
    Special private classes for the module.
    It's important that classes remain in one file as when they are in individual files they can be loaded in the wrong
    order which can cause 'type not found' errors.
    It also breaks IDEs as they can't find the type definition.

<#
    This class converts shorthand git diffs into human readable status
