Cups and Balls Fully Parametric Cup

** Work in Progress... **
# Cups and Balls Cup Generator
This is a customizable cup for the classic Cups and Balls magic routine. It's possible to make a cup of any size that can resemble a classic straight cup to a Paul-fox like cup to something contemporary.

*Resulting STL may need to be "fixed" with a mesh tool once generated before printing.*

### What needs to be added still:
1. Option to generate an insert for a magnet to make a combo chop-cup.
2. Create different styles of curves for the top of the cup as it is much too easy to end up with an ugly phallic result.
