Add Match Regular Expression sub VI

[wiebe@CARYA]

The Match Regular Expression is worth it's weight in gold, once you get used to it. There is some functionality missing though:

1) The begin\end positions of the capturing groups are not available. These positions can be more useful than the matching strings.

2) It's unnecessary slow when the string results are not needed.

3) The results are output terminals, making it hard to adapt to dynamic inputs. A results array is sometimes more convenient. For example a pattern is entered in a GUI.

I use the attached VI (based on the same API) a lot, to bypass these limitations. I think it would be useful in the LabVIEW palette, under String>Advanced String Functions.
