java.util.List<ConditionResult>	evaluateRules(java.lang.String ruleName, java.util.List inputData) Evaluate a named rule set
boolean	isRegistered(java.lang.String ruleName)
boolean	registerRules(java.lang.String ruleName, java.lang.String[] conditions, java.lang.String[] paramNames) Method that takes the rules and registers them against the rules engine the name parameter is the key to getting those things back so it needs to be unique (probably method signature)
