MSGFScore is an integer, not float
Added empty init for dataformats module
Changed a docstring
Changed sort functions to sort info from db records by key
Lookup all protein group content from sqlite before it is sorted in a big join
Switched psm / protpepmap fetching to multi table join
More than one (temporary) master may be found in a protein group if they share all peptides. We will sort later
Index of database records of a protein group return should be constants
Sorting protein groups gets function call and counting protein hits in group too.
Removing some crap, fixing a docstring, and adding function arguments
Created main protein group psm generator
