; PURPOSE: (one line)
;   Convert declination in radians to an ASCII string.
; DESCRIPTION:
;  
; CATEGORY:
;  Astronomy

; INPUTS:
;  dec - Declination, in radians, to be converted to a string.  May
;                  a vector, in which case the output will be a vector.
; OPTIONAL INPUT PARAMETERS:
;  places - Resolution of output string (integer).
