skillStringXmlEditor.py

#!/usr/bin/env python3

"""
Python 3.x.x

Used for modifying the string XML for skills, to change skill values
(integers found in each level description).

Supports adding/subtracting, multiplying, setting,
but could easily be tweaked for a lot of things.

Prints the number of individual values changed, for verification purposes.
