in plot api, pass fig and ax to give more control to the user's code

[ksachdeva]

Thanks for this great library.

Purpose of this modification:
I have been using it with a multivariate time series dataset. Each dimension gets its own plot and wanted to make use of subplots to see all the dimensions at the same time (in a grid for e.g.)

Notes:
a) I have added fig as the parameter to the plotting API as well. Generally, it is not required. I have done it so as to not create a situation where the number of return values is 1. This way your function always return 2 values (the tuple).

b) Instead of using plt.xlim and plt.ylim, I am using ax.set_xlim & ax.set_ylim. This should work for previous version and for this modification as well.

c) For now if the method is 'discrete' then passed fig and axes are ignored since the plot_binom function creates subplots internally.
