- Ability to start rule axis execution at a specific rule by adding the [ axisName: ruleName ] entry to the coordinate name.  In other words, bind the rule name to the RULE axis and you're golden.
- containsCell() simplified now that multiMatch is removed.  There is now containsCell(Map coordinate) and containsCell(Map coordinate, boolean useDefault).  The later API will return true if a defaultValue is set, and the useDefault argument is true.
