Just a tiny adjunct program for @chauffeur_afni.

Small program to calculate how to evenly space a certain number of
slices within each view plane of a dset.  Returns three numbers: the
'delta slices' in the three view planes (in the order of the input
dset's orientation).

++ constructed by PA Taylor (NIMH, NIH, USA).
