Change debug/trace using print out statements to use logging instead

[ltddev]

The current code uses simple print strings at various points in the code flow to provide debug and tracing information to the developer. These messages are not meant for the user. A boolean flag is used to turn on or off this printing.

Since logging is built-in and is the standard means to provide this function convert all the print strings to logging statements, whether to file or to std out.

You might take a look at thetraced decorator at: https://github.com/671620616/Tools/blob/master/Source/common_decorators.py it could be modified to do logging instead of printing.
