Disabled all print statements as precaution

So that you don't try running it on a 8 MB file and expect it to run as fast as it can while it desperately tries to print every single galaxy and all of its data.

See lines 243-250 for useful prints, 245 prints all galaxy dicts, 247 prints all parameter names, and 250 prints 3 lists, each containing all of the values for a given parameter.
