GetRuleMemoization() public method

* Given a rule number and a start token index number, return * MEMO_RULE_UNKNOWN if the rule has not parsed input starting from * start index. If this rule has parsed input starting from the * start index before, then return where the rule stopped parsing. * It returns the index of the last token matched by the rule. *

* For now we use a hashtable and just the slow Object-based one. * Later, we can make a special one for ints and also one that * tosses out data after we commit past input position i. *
