set_stim_col_const

 Figures out which data columns correspond to different database fields in the stimulus table

 var_list is a cell string containing field names
 SD is a structure with constants (column ids) assigned for the following
 fields:

 STIM_ID -- stimulus ID
 NAME -- stimulus name
 DESC -- stimulus description
 ARTIST -- artist
 ALBUM -- album
 GENRE -- genre
 FORMAT -- file format
 SIZE -- file size
 DURATION -- duration of file HH:MM:SS
 YEAR -- year of recording
 BIT_RATE -- compression bit rate
 SAMPRATE -- sampling rate
 SAMPSIZE -- number of bits per sample?
 CHANS -- number of channels
 FNAME -- path to file
