Dynamic Patching with Python for Record Keeping of ALL Library Output

DynPatch.py

"""
This was a weird and niche case scenario. I had a problem where basically, I wanted to capture as much output from the script as possible and 
display it on a web UI as a sort of live feed. However, this was only possible to the extent of writing the logs to a logger, or controlling 
the code I wrote at the time.

Then I thought - simply; almost every library at the end of the day, even if it calls a logger class, will call print or 
some form of sys.stdout. If we override print(), we handle most of the general cases where output gets printed from other 
libraries, and can have a better result when trying to detect errors during the runtime.
