// C3GPLibParseComposeFile takes a directory path specified by the test configuration and 
// parses the video & audio data within the single file inside the directory.  Optionally,
// this class can parse then use the data retrieved to compose a copy of the original file.  
// The output files will reside in a user-specificed output directory, using the same name as the
// original file.  An extra option is to compare the input & output files' video & audio data.
