The save_plot() function now adjusts the font size of the plot title.
Created function make_animated_gif_map() which creates animated gifs from the layers of a 3-D matrix where each layer represents a map.
Updated the function Helpers/get_radio_astr_exclusions() to give the user more control over the output. Correspondingly updated existing calls to this function.
Adding a simulation parameter 'unused_channels' to specify channels which are in the chan_list but are universally not available for whitespace use (in the US, these are channels 3 and 4). The new file Helpers/remove_unused_channels.m will allow you to wipe out (either with zeros or by removing those layers) these channels in a 3-D map matrix.

Currently other files provide this functionality themselves but in the future we will update them to go through this new function for uniformity and internationalization.
Added a file which will plot the towers on a single channel and their protected regions.
Added a file which will choose a random point (uniform distribution) in a given region.
Added a file which will quickly display a map (useful for draft purposes).
