[TxMt] Better JavaScript functions

"That'll work to" - Jet Li's The One :)

<That page shows 'private' functions, 'privileged' functions, and  
public functions. If the examples don't answer your question, feel  
free to contact me off-list (as I fear we're straying far from  
TextMate topics. ;)>

Thanks a lot Gavin, great page!
I got the idea from Crockford from the beginning, but this seems a
