Adding a Fedora test of property values

@WIP - The specs are broken.
Adding ValueParser concept

I need to find the appropriate predicate. A predicate has a
corresponding value parser.
Adding bin/rails so the generator works
Tidying up Guardfile

Explaining the differences between the various spec contexts.
@WIP Ongoing broken tests
Crafting a Predicate data structure

I want to get out of the ActiveRecord business as some predicates may
not be defined in the database, and we should handle things
more gracefully than ActiveRecord may typically allow.
Adding Hydramata::Work::Predicates.find

Teasing apart the storage and the datas tructure and providing
some semblance of a mapper.
Easing restrictions on the PredicateStorage
Updating .gitignore
Adding ability to lookup ValueParsers

There are some vestigial methods in here. As part of resolving this
branch I will clean up those vestigial components.

Then merge into master.
Renaming predicate attributes
Fedora to In Memory complets end to end
Cleaning up code coverage

There are still vestigial elements, but those are perhaps a TODO item
for later.
Fixing the build. Hope it works on Travis
Attempting to get Travis to pass

By moving the migrations into the generator, I know that Rails has
been loaded and the context was properly defined.

Prior to this change, when spec/internal did not exist, then the
`rake app:db:create` task was not registered (as it is defined as part
of the spec/internal application).
Adjusting comparisons

Silly travis, please pass.
