/*
 * Styles define a set of columns for each player, and information about those
 * columns, like what Instruments are used play those columns and what track 
 * to use to populate the column's notes.
 * A "track" is the term used to descibe a particular vertical sting of note 
 * in NoteData.
 * A "column" is the term used to describe the vertical string of notes that 
 * a player sees on the screen while they're playing.  Column notes are 
 * picked from a track, but columns and tracks don't have a 1-to-1 
 * correspondance.  For example, dance-versus has 8 columns but only 4 tracks
 * because two players place from the same set of 4 tracks.
