Added source array/name/directory files.
Tweaked rms_I.
Tweaked.
Added directory names, changed method of finding peak_pol from peakData() to getting it from pr.def.
It now catches NANs in peak_P, and I changed the names of the source_names and source_dirs files.
Added vector_logs keyword, which allows you to not print vector logs when making a map that includes two distinct sources.  Added vector_scale_bolo keyword, which allows for making smaller vectors in the case where the bolo map doesn't zoom out very much.  Corrected mistake: divided CARMA_vector_limit by 3600 to convert ot degrees.  Added vwidth_bolo and vwidth_scale_CARMA to allow vector-size tweaking on bolo plots.  Changed v_limit_bol to v_limit_bolo.  Changed the method of finding the maximum polarization...it now finds the actual maximum, as opposed to the largest pol of a plotted vector.  I may change this back.  I also save peak_pol to pr.def, with the source name appended.  I also changed the format of the x-axis labels to decimal seconds from seconds.
I no longer set peak pol here; I set it in make_TADPlots.
Tweaked polCalc_FITS() -- I now mask not only the PA and PA_rms FITS files based on rms_I and rms_QU, but I also mask the pol, pct, and pct_rms FITS files.
