1.  a.   How can I randomly pick a point in a point process.

     b.    How can I exactly refer to a point in a point process And
possibly delete it..


2.  How can we change(add or delete) the total number of points in a process
as per some function.
     Lets say Poisson arrival of points or delete(deactivate) points as per
Poisson dist.

3.  How can we simulate mobility of points in a point process.
