Changes for Parallel Version Only

These changes are by Y. Wang (ANL), unless otherwise noted.

• The FTABLE element (3d field table) is now parallel capable.
• Aperture determination using the line-search method can now use a much larger number of cores. Before, the number of cores was limited to the number of steps along the line. Now, it is limited to the number of lines times the number of steps. (M. Borland, ANL.)
• The SCRIPT element is now parallel-compatible. However, the script does not use parallel resources.
• A bug was fixed for the parallel version that caused a crash when PFILTER was used with DELTA_LIMIT greater than zero. This was reported by J. Frederico (SLAC).
• Several improvements were made for parallel optimization: The population log output now includes statistical information on the optimization function values. The population size will be set to the number of processors if the user sets the population size too small. For swarm optimization, the initial points are spread within the whole space, instead of a local neighbourhood, for global optimization.
• Implemented a new function for calculating the sparsely-populated histograms efficiently, which allowed parallelizing the RFMODE element.
