45  * Scan a set of directories for suggestions
46  *
47  * @todo Provide a progress dialog, with a Cancel button
48  * @todo Modifications to files opened in the background should
49  * get saved!
50  *
51  * @todo It's probably overkill for me to go and open the Documents
52  * for every file I'm scanning; a buffered file reader inside of
53  * a StringReader would do the trick, provided SourceScanner would
54  * accept a String argument. That's a simple refactoring operation
55  * since most of the internals in the SourceScanner is dealing with
56  * the String value of the document. I should probably do a getDocument
57  * though in case a file is already open - that way I get the current
58  * (edited, not saved) version of the file which is what we want - or
59  * it not?
