Implement the new fixed source bank model. For a fixed source calcultion the primary source bank is not allocated memory and source particles can not be read/written to files. The source particles for each history are now sampled at the start of initialize_history() through call to sample_external_source() with the appropriate seed. The timing stats for sampling has been removed from the output since this processing is now part of the transport timer
