Detailed Description

Loader for event data from Nexus files with parallelism based on multiple processes (MPI or MultiProcessing) for performance.

This class provides integration of the low level loader component Parallel::IO::EventLoader with higher level concepts such as DataObjects::EventWorkspace and the instrument.
