-Enhanced Rule Axis so that the output Map can be accessed as part of the condition, and the output map would be up-to-date per the latest update from an executing cell.  Prior, it was gathering which rule axis columns fired, and then executing cells, essentially only providing access to the output map as it appear when the method was original accessed.
- Added support for RuleStop.  This method can be called, and rule execution is stopped.
- When a cube runs that has a rule axis in it, the '_rule' entry is added to the output map, which contains the status of whether ruleStop was called (true) or not (false).
