HW #22

[chasestarr]

In this homework we will practice using our new Particle class. Use this week's exercise for help.

_Description:_
When you click the mouse, create a new particle at the mouse location. This particle should have a force applied to it as well. Take a look at the Processing reference for information on using the mouse click to trigger events.
