1. Added fariba's new matlab files (after some fixing up and consolidation). plot_ctf can now handle anything generated by the gui that you throw at it. Made sure the file names are consistent, and removed the extra loader function which is not necessary. Basic testing performed, although I would double check the plots you get for consistency. 2. Fixed up some problems with the noise source model (not that they are doing anything yet) which was preventing relevant parameters from being saved. 3. Fixed up the loader code to rely on the plc module for plc_value replication across the unspecified dimension (apparently this results in a performance boost) and removed associated warnings.  4. Modified the loader code to setup noise sources a bit more fully in preparation for doing something useful with them in the near future.
