Filtering FIle Types

[Peter M. Brigham]

Here's an expanded version -- feed it a list of filetypes and get them all at once:

function filterByType pFileList, pTypeList
   -- assuming pTypeList is of the form "jpg,png,gif" (for instance)
   repeat for each item t in pTypeList
      put pFileList into workingList
      filter workingList by ("*." & t)
      put workingList & cr after outList
   end repeat
   return char 1 to -2 of outList
end filterByType
