Added a function to load a Q file with 'standard' file name & location. Also separated the foreground and global signal alms in the compare_hybrid_grid function so that I could compare the ratio of the global signal to the fgs in the recovered a00.
Changed the gsm_degrade_map function so that it will loop over many files in a folder. Later realized I didn't actually need the maps at this point, so I guess this was kinda pointless.
Added three functions to monte_carlo_analysis. load_mc_data loads mc_data from standard locations & filenames. foreground_hist makes a histogram of the global average of all of the visibilities.... it doesn't actually make a histogram of the true sky global signal. I need to re-write it. construct_gs_hist makes a histogram of recovered global signals for each y vector generated in the mpi_monte_carlo code.
