/*
Art 3001 Line Assignment
-Four quadrants with moving colored lines, each quadrant having different constraints and using random elements for drawing
-Quadrant 1 has lines moving along the  vertical edges
-Quadrant 2 has lines moving along the horizontal edges
-Quadrant 3 has lines moving along all edges
-Quadrant 4 has lines moving anywhere inside the quadrant
