  Class and Description
  DataPartitioner This is the base class for all data partitioner.
  LocalTaskQueue This class provides a way of dynamic task distribution to multiple workers in local multi-threaded environments.
  ParForBody Wrapper for exchanging parfor body data structures.
  ParWorker Super class for master/worker pattern implementations.
  RemoteParForJobReturn Wrapper for job return of ParFor REMOTE for transferring statistics and result symbol table.
  ResultMerge Due to independence of all iterations, any result has the following properties: (1) non local var, (2) matrix object, and (3) completely independent.
  ResultMergeTaggedMatrixIndexes This class serves as composite key for the remote result merge job (for any data format) in order to sort on both matrix indexes and tag but group all blocks according to matrix indexes only.
  Task A task is a logical group of one or multiple iterations (each iteration is assigned to exactly one task).
  Task.TaskType
  TaskPartitioner This is the base class for all task partitioner.
  TaskPartitionerFactoring This factoring task partitioner virtually iterates over the given FOR loop (from, to, incr), creates iterations and group them to tasks.
  TaskPartitionerFixedsize This naive task partitioner virtually iterates over the given FOR loop (from, to, incr), creates iterations and group them to tasks according to the given task size.
