Good work, Rob.

I suggest you the following interface:

1) Rename the class from 'Regex' to 'RegExp'.

2) Make a virtual class '.RegExpSubmatches' and make a property 'SubMatch' 
that returns it.

3) '.RegExpSubmatches' will have only one method: '_get', and will return a 
virtual class '.RegExpSubmatch'.

4) The virtual class '.RegExpSubmatch' will have three properties:
- Text, that will act as the old method SubMatch(Index).
- Offset, that will act as the old method SubMatchOffset(Index).
- Count, that will act as the old method SubMatchCount(Index).

This way, we could have the following syntax:

MyRegExp = NEW RegExp("...", "...")

PRINT MyRegExp.SubMatch[1].Text
...

If you are not easy with virtual classes, look at the ListBox code to see how 
it returns ListBox items.

As for a 'MATCH' keyword, this would need support from the interpreter, 
exactly like the Eval() subroutine. So I'm not sure I will do it now.
