#27 Lookaheads / lookbehinds are counted as groups

[Eyal Roth]

Lookaheads / lookbehinds are counted as groups, which is incorrect and incompattible with standard java library.

java.util.regex.Pattern.compile("(?!xyz)").matcher("").groupCount() // 0

new jregex.Pattern("(?!xyz)").matcher("").groupCount() // 1 - WRONG!

This is actually preventing me from using the library entirely :(
