Documentation for nested methods

[Hazboun6]

I've added in a file of plotting functions, PSS_plot.py, that I've been populating with common pots the user might want as they play with the signal. I've added the methods to the Signal class so that all ones needs to do is call the plot type and the function uses the dictionary to build a nice looking plot with the correct parameters. However, the normal docstring that appears, and more importantly the nice help one gets when in a jupyter noteboook (shift+tab, where the full signature appears with all of the needed variables) does not appear. The command sitting in signal.py appears instead. Since these plotting functions have a number of options it would be nice for this to appear. Any thoughts?

@Hazboun6 is this still relevant or should we close it?

It's sort of relevant, but maybe should have been a question posed to StackExchange rather than as an issue? I think we can get around this by making the plotting scripts be classes rather than methods, so that the docstrings will just get inherited. I will close the issue.
