Since we don't want the name of the tool to reflect the fact that
it is using yard internally (this is an implementation detail), rename
the face to `strings`. Now when one wishes to generate documentation,
`puppet strings` will be used rather than `puppet yardoc`.
Add tests to ensure that the face (puppet yardoc) works from end to
end. In other words, ensure that when given a module, puppet yardoc can
successfully evaluate the .pp and .rb files present in the module and
produce the expected HTML.
Add tests for the remaining two Puppet-specific handlers that were
not tested in the previous commit. Specifically, add tests for the
3.x function handler and the host class handler.
Prior to this commit there was no testing around the pops component.
Since most of the API in the pops component is private, there aren't
very many things to test, so add just a few test cases.
Additionally rename a previous spec file and make some changes to
the Gemfile.
