Class ZeroOrMore

Rule --+
       |
      ZeroOrMore

Match a rule ad infinitum. This rule is similar to the Optional() rule. While this one only matches if the subrule matches 0 or 1 times, the ZeroOrMore rule matches at any time. This rule tries to consume as much input as possible.

Method Summary
	`__init__(self, rule)` Initialize this rule with a subrule.
	`__str__(self)` Return a human readable representation of the rule.
	`match(self, input_reader)` Match the input against the subrule.

	`__add__(self, second_rule)` Define an operator to concat two rules.
	`__or__(self, second_rule)` Define an operator to concat two rules via OR.
	`callAction(self, param)` Call the action attached to this rule.
	`hide(self)` Tell this rule to not produce any token output.
	`returnToken(self, token)` Helper function encapsulating the hide()-functionality.
	`setAction(self, action)` Set the action to execute on a rule match.
