SourcePopulation.cc: use print_ctl to control catalogue print to cout. Galplotdef.cc .h:  sourcepop1.print_ctl. gen_source_populatin.cc: sourcepop1.print_ctl from galplotdef

gen_source_population.cc: if(1) generate Fermi catalogue to file, for possible control later. start and end to cout

SourcePopulation.h add print_ctl, SourcePopulation.cc use print_ctl for cout of sources, init print_crl=0, not yet in Galplotdef

SourcePopulation.cc: cout sourcepop5 simulation if sourcepop5.verbose!=4, sourcepop5.verbose=4 always set in gen_source_population.cc independent of galplotdef.verbose. So this version will never cout that so need to do that

SourcePopulation.cc: plot model above and below sensivitity limit, plot_control=3, gen_source_population.cc use this

SourcePopulation.cc: replace flux_detection_limit by flux_detection_limit_sensitivity_file in selections, flux_detection_limit is user-defined and constant, used in gen_source_population.cc

gen_source_population.cc: output summary table for sources above and below threshold from threshold file

SourcePopulation.cc gen_sourcepopulation.cc use  galdef_ID, psfile_tag for idl plots. genidlplots used plot file name

SourcePopulation.h add IDL_plot_control, IDL_psym. SourcePopulation.cc use these in plotting. gen_source_population.cc: apply these in plots
