This python program displays, saves and plots the readings from the Radio Shack RS22-168A multi-meter serial port

Thanks to https://github.com/Ostheer/Voltcraft_ME-32_RS-232 for their progam that I used as a starting point.

I actually use a CH340 USB to serial Cable with Windows 10. The correct serial port must be specified. User can change the sample_time in integer seconds. The time is not exact using this method. Program overwrites the CSV file and plot image file if they already exist. Ctrl-c stops the program and displays the plot. User must close plot to end the program.
