Move data collection from csv into a function

Data needed for plotting is collected from csv file and returned to
plotting routine.  This will allow a loop to be generated for adding
gray-scale shading.
moved data processing and labeling to functions
minor changes
added fill_between max and min
Fixed problem with rhs3 gray-scale

was using min instead of max
fix errors in title, file & other plot info
fixes for some plots that were not showing gray scale

a few are still not working
trying to fix problem with tot_res_output

Not working yet
fix tot_res_output
