Simulate Baddeley-Silverman Cell Process
Generates a random point pattern using the cell process. The $K$ function of the cell process is indistinguishable from the $K$ function of Complete Spatial Randomness.

In the function

The cell process is then generated in these tiles.
Some of the resulting random points may lie outside the window
if they do, they are deleted.
The result is a point pattern inside the window
