Member Enumeration Documentation

"ParallelizationStrategy" to employ.

SYNC_SOURCES assumes that the data added on each processor are independent and relatively small. Calling the prepare_for_use() method with this ParallelizationStrategy will copy remote data from other processors, so all interpolation can be performed locally.

Other ParallelizationStrategy techniques will be implemented as needed.
