Version 2.3.1

Update to README and setup.py metadata

Version 2.3.0

Updated and tested to work without errors (at least the demos) with:

• Python 3.9
• wxPython 4.1.1
• matplotlib 3.5.2

NOTE: picking functionality is disabled / broken -- it needs to be updated for modern wxPython (and maybe MPL, too)

Version 2.2.2

Bug fix for modern except syntax

Version 2.2.0

First version to support wxPython 4.* (Phoenix)

Release 2.1.0dev

This is a snapshot of the state of the lib before updating to wxPython 4 (Phoenix).

It had some issues, but might be worth loking at if you need to use older wxPython versions. Though I suspect that most of the modernization will work with recent wxPython "Classic" versions.
