simPts: Simulates point process on a rectangular grid
Description
Generates a set of points from either a homogeneous or inhomogeneous Poisson process
with optional clustering. This is a wrapper function for rpoispp from
the spatstat package. The intensity is defined by covariates on a grid,
an intensity formula and parameters. The correlation structure is defined by the model
and the correlation parameters.

x and y are the mid points of the grid cells; the order
of the rows must match the formulation for function im
