Shay Carter 772613b30d First pass at updating documentation for v20
- removed all images that don't apply for v20
- removed several extra files that aren't necessary (in the docs/pdf/ and docs/python/ directories)
- renamed some images that were preserved that had random character names, to something descriptive

## New Map Editor / View
### Adding a New Map Editor
This can be done in two ways: using the **file menu** and **right clicking** on the tab bar.
Using the file menu, simply go to: **File > New Map**.
This opens a new map editor tab with the default projection (CONUS Polar Stereographic).

To use the tab bar, **right-click** on or next to any tab and select **New Editor**

### Renaming Map Editor
Any of the map editor tabs can be renamed. This can be particularly helpful if you have multiple tabs, with a different focus on each (ie. different geographic reigon, different types of data, etc).
