*
* Changes:
* 17-May-04: Only scans if the edit mode is either 'java' or the default mode
* : Ignores declarations that are in multiline comments
* 08-Jun-04: If an infinite loop is hit (1000 iterations) in the comment
* : parsing, it now opens the default save dialog, rather than
* : just returning.
