matchChunk to find fontNames

[Claudi Cornaz]

Thanks Björnke, Eric  and Marielle,

You all helped me.

In the mean time I got the matchChunkpart also worked out, and am 
putting it all together now.

I will try to make a complete textMenu example, with all the features 
you ever wanted,
plus a few more I hope (well, we will see about that one)

Regex can be really fun and it's not quite that difficult after all and 
tremendously usefull.
It took me a while but I learned quite a lot, and all though I don't 
know every thing I am
certainly not afraid of regex anymore.

I am putting the last bits and pieces together and smooth the whole 
thing a bit.
It's still quite experimental at the moment, but as soon as it's 
"descent" I will post it

In the mean time all the best.

Claudi
