Write a script that will create a two-dimensional patch object with just three vertices and one face connecting them. The x and y coordinates of the three vertices will be random real numbers in the range from 0 to 1. The lines used for the edges should be black with a width of 3, and the face should be grey. The axes (both x and y) should go from 0 to 1. For example, depending on what the random numbers are, the Figure Window might look like the Figure.
