Blank-Canvas program which plots a set of random points on a graph. Two players are then each asked to write an inequality function so as to try and cover as many points on the graph as possible.

runghc point-plotter.hs to run, and CTRL+C to quit.

• y <= [(2,3),(0.5,2)] is like y <= 2x^3 + (0.5)x^2
• y >= [(-0.1,0)] is like y >= (-0.1)

If you're using polynomials of degree > 1, make your coefficients small --- they are plotted on a 600x600 graph, so even x^2 goes off the charts fairly quickly.

tested on an Ubuntu 14.04 virtualbox under Vagrant.
