[BUG] When program crashes, pretty print error message

[gregbell26]

Description

Issue

When the program crashes, a large stack trace is generated, and when running from compiled source, this causes the program to completely exit so the error message cannot be seen.

Steps to recreate

Enter in an invalid input for an overridden max points value or assignment scaling (like a string).

Solution

Catch the error and cleanly report where it occurs then wait for the user to press any key to close the application.

Acceptance Criteria

• All run-time errors that put the application into an unrecoverable state are caught
• 'Nicer' error messages are printed to the user
• Error messages include the module where the error occurred
• Error messages include the type of run time error
• Program waits for the user to acknowledge the error before exiting with a non-zero status code.
