Make the base FacetClass a trait instead of an abstract class
Consolidate facet data parsing into the SolrQueryParser class
Import cleanup
Merge branch 'master' of github.com:mikesname/docview
Various minor cleanups to facet code and imports
Rationalise Json serialization/deserialization by always putting the
Json format object as an implicit value of the type's companion object,
rather than importing it where needed.
Make json formats lazy so they don't depend on initialization order
(although they're place last anyhow.) Place some enums within a
smaller scope and remove some old cruft.
