Given the number of entities each processor intends to write, do necessary communication and create dataset on root, passing back misc info to each proc.

Parameters

creator	Functor to do actual dataset creation. Used only on root process.
num_datasets	The number of datasets to create.
groups	Third argument passed to DataSetCreator. Array of length num_datasets pr NULL.
num_owned_entities	The number of entities this proc will write. Array of length num_datasets .
offsets_out	Output: The offset in the dataset at which this process should write. Array of length num_datasets .
max_proc_ents_out	Output: The maximun number of entities that any proc will write Array of length num_datasets .
total_ents_out	Output: The size of the created dataset (sum of counts over all procs) Array of length num_datasets .

Pack set data for communication.

If set_data_length is insufficient for the set data, the length entries at indices 1, 2, and 3 of set_data will be set with the necessary lengths, but no data will be written to set_data beyond that.
