Hi Gernot

I have modified the functions SetNpx, SetNpy, SetNpz
 -adding warnings in case of illegal values
 -using the maximum possible value if the specified value is greater
 -adding comments explaining the meaning of fNpx,y,z

I have also added comments in the GetRandom functions to point
to the setNpx,y,z functions.

Thanks for thsi remark.
