Two level compiler should have a way of back reference. #11

VOW_CON_+.CON=> will ditch the second consonant, but right now that can be any consonant. What if it only needs to be removed if it is the same as the match in the middle context? For this a backreference to the match should be introduced.

Back referecing is now possible regarding matches on the left side of the middle context. Meaning that this works:

VOW.(CON).+_(1)_=>

Capturing is done by placing the context between brackets, referencing to the same match is done by (number of group). This rule will only ditch the consonant, if it is the same! :)
