ElementMulticategoryFilter

Description:
A filter used to find elements whose category matches any of a given set of categories.

Remarks:
This filter is a quick filter. Quick filters operate only on the ElementRecord, a low-memory class which has a limited interface to read element properties. Elements which are rejected by a quick filter will not be expanded in memory.
