00025 //       Class : FilenameUnifier
00026 // Description : This static class does the job of converting
00027 //               filenames from relative to absolute to canonical or
00028 //               whatever is appropriate.  Its main purpose is to
00029 //               allow us to write relative pathnames to the bam file
00030 //               and turn them back into absolute pathnames on read,
00031 //               so that a given bam file does not get tied to
00032 //               absolute pathnames.
