[in]	ncut	Number of cutoffs
[in]	cuts	Array of cutoffs
[out]	nval_ret	Number of samples in the output array

Remarks: This function considers the segment [x1,x2] and subdivises it; into 'ndisc' intervals. The endpoints of each interval correspond; to two points in the space; At each endpoint, the target variable is interpolated from the grid; If the target variable values cross a cutoff, the coordinates of; the intersection are calculated.; The program returns the list of all these intersection coordinates
