3.0.0 to 3.1.0

The Procedural Scheduling API has one breaking change in Aerie v3.1.0: the functionality of filterLongerThan and filterShorterThan methods have been inverted to be more consistent with other filter methods. filterLongerThan(duration) will now include all events longer than duration, not remove them. See aerie-ui#1587 for details. If you are using these functions in your code, you should invert them as needed to achieve the same functionality in v3.1.0.
