/*
Mac OS X implementation of FilenameField
 only the equals operator will be case-sensitive.  substring search, ends, starts, etc. will be case-insensitive, 
 to make things like "filename ends .mp3" easier
 
TODO: it'd be massive overhead, but it'd be more correct to check if the file system is actually case sensitive (for the path being searched)
