added visualization of channels and option to manually select bad channels in rd_runMEGPreproc.m
added rd_MEG_AnalysisFlow_SingleTone.m. This is modified from Adeens script of a similar name, and it is now in working order - can completely run through the script with singletone data and get sensible output.
