/*Title: Sailboat

By: Alex Olechnowicz

Date Submitted: October 4, 2017

Description: The sailboat moves horizontaly towards the mouse. The clouds loop through randomly.
When clicking in the water, the third that was clicked with corespond with eithor R,G, or B
and will tint that colour. Three lines are drawn towards where the mouse clicks in the water.*/
