Finalized Metis PHP Class compiler script. Tweaked functions that need to be modified, eliminated double arrays and went with key/val instead. Line-by-line modification now checks for global var call and ignores the line if it has it. This eliminates error-generating global $nodeList and global $directoryHostingMetis lines. Modified metisInit() to use a different var name for dir w/out root to avoid line-by-line function checking issues.
