* Output:
* out_NeX: number of events in each grid cell. [1...N] (i.e. it refers to the subset of points in "points").
* NeT: total no of events in each time step (i.e., sum of out_NeX). [0...nts-1]
* ReT: total seismicity rate at the end of each time step. [0...nts-1]
* all_NeT: no of events binned in space and time [0...nts-1][1...N];
* R: seismicity rate at the time of the earthquakes given in cat (used for first term of LogLikelihood).
*
* NB: assumes that times, cat, DCFS, NTS, times are always the same (each time function is called), since many static internal structures are initialized in the first function call.
