Simulate Matern Model I
Generate a random point pattern, a simulated realisation of the
rMaternI(kappa, r, win = owin(c(0,1),c(0,1)), stationary=TRUE)
- Intensity of the Poisson process of proposal points. A single positive number.
- Inhibition distance.
- Window in which to simulate the pattern.

A proposal point is then deleted if it lies within

of another proposal point. Otherwise it is retained.
The retained points constitute
