;    Name:               make_some_sp_cubes
;
;    Purpose:            This is a wrapper that accepts vectors of SP obsid names and repeatedly invokes sp_make_cube_index.pro 
;                        (which builds multiple data cube products from spectropolarimeter data and save in iris FITS format).
;                        sp_make_cube_index also makes corresponding overview SP image products, i.e., images or movies, as appropriate.
;
;    Input Parameters:   dstring -- the start time/date string of a hinode spectropolarimeter observation.  Required
;
;    Keyword Parameters:
; 
;
;    Output:             driver for sp_make_cube_index.pro that accepts a vector of obsid strings/names.   (Can be a vector of 'one'.)
