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`.
In order to make the code more readable, separate the tests into
different files for each handler. Additionally, extract the helper
methods into a separate module which may be included as needed.
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.
Begin to test the YARD handlers written for the puppet language.
Add basic tests for the defined type and puppet 4 function
handlers. In addition, make changes to the spec helper to make it
easier to work with YARD Registries for testing purposes.
Add spec tests for Puppet face component, mainly around error checking.
Due to the use of `puppet module list`, the behavior of the `modules`
and `server` actions are not very feasible to test via spec testing.
Additionally, make a few minor changes to the gem file, and make a
small change in `check_required_features` to reflect the fact that
this module will no longer support anything earlier than Ruby 1.9.
