'  Initialize the zip object.  Because we're creating

'  Append a directory tree.  The AppendFiles does
'  not read the file contents or append them to the zip
'  object in memory.  It simply appends references
'  to the files so that when WriteExe (or WriteZipAndClose,
'  or WriteZip, etc.) is called, the files are compressed
'  and added to the archive.
