check_levels

Adding some at-present missing functionality, or functions
unlikely to be added to the base 'xpose' package.  This includes some
diagnostic plots that have been missing in translation from 'xpose4',
but also some useful features that truly extend the capabilities of what
can be done with 'xpose'. These extensions include the concept of a set of
'xpose' objects, and diagnostics for likelihood-based models.
