[PyFeyn] Object-orientation

[Jesse Dunietz]

Hello,

I'm using PyFeyn for a project, and I'm immensely puzzled as to why
there is canvas and current-diagram information kept at the class
level for the FeynDiagram class.  Why would you not give each diagram
object its own canvas, perhaps with the option of specifying a canvas
in the constructor?  I'm having an impossible time trying to draw
multiple diagrams from my code.

Thanks,
Jesse Dunietz
