Subject: Reorganization and comments

Broke out the structs for a poem into their own file: src/recite.rs.
Also put the 'prefresh' function into it's own file: src/recite/path.rs.
Commented most of the parser code (including structs and helper methods
related to parsing (i.e. Verse, Stanza, Meter, Poem)). Renamed any
instance of the 'paths' variable to 'path'.
