tergen1d(level)

1D random terrain generator

tergen1d(level) is a random terrain generator in 1 dimension. It begins by dividing a line segement between (0,0) and (1,0). Next, it adds a random value between (-1,1) to the y-value of the dividing point at x=0.5. The two new line segments are then split in the same way but the range of the new y-value addition is decreased by half (-0.5,0.5). This is repeated level times.
