Added functionality for matplotlib inline backend
Created by: tjma12
The %matplotlib inline
functionality in Jupyter notebooks was not working because the matplotlib inline backend doesn't have a FigureManagerBase
class. This PR adds a check to use the correct methods if the inline backend is called. I tested this in a jupyterhub notebook and was able to render inline figures.
Fixes #964 (closed).
