Refactor the code in the strings face and extract much of the functionality
into a separate library in order to make the code more readable and
sustainable. Additionally, remove the `modules` action from the face
since it does not have a clear use case currently. However since the `server`
action depends on it, and it may be helpful to add other features in the future,
extract the functionality previously contained in `modules` into a helper
method.
Prior to this commit, the handlers and code objects which dealt with
puppet functions were referred to as `FutureParserFunctions` and
`ParseFunctions`. This naming convention will not make very much
sense going forward when the future parser becomes the primary
parser. Therefor, rename `FutureParserFunctions` to `Puppet4xFunctions`
and `ParserFunctions` to `Puppet3xFunctions`.
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.
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.
