Class org.as2lib.regexp.node.GroupCurly

Description

GroupCurly handles the curly-brace style repetition with a specified minimum and maximum occurrences in deterministic cases. This is an iterative optimization over the Prolog and Loop system which would handle this in a recursive way. The * quantifier is handled as a special case. This class saves group settings so that the groups are unset when backing off of a group match.
