+Demonstrates one way of embedding Matplotlib figures into a PySimpleGUI window.
+
+Basic steps are:
+ * Create a Canvas Element
+ * Layout form
+ * Display form (NON BLOCKING)
+ * Draw plots onto convas
+ * Display form (BLOCKING)
+ 
+ Based on information from: https://matplotlib.org/3.1.0/gallery/user_interfaces/embedding_in_tk_sgskip.html
