.VJE file format and other Visual Edwards Updates

Visual Edwards update: The project now saves and imports data in its own file format: .vje (which stands for Visual Jonathan Edwards). A .vje file stores all data parameters and instructions necessary to recreate a visualization with all of its media files. All in a 1 KB file. Also added an adjustable transparency option which gives an increased sense of dimension, as well as the ability to isolate various terms or phrase references in WJE 1-26 along with their immediate connections. Now able export to transparent scalable vector graphic format which is great for hi-res zooming in videos. The project is tested on Windows 10 and runs on Python 3.7.
