;+ NAME:
; dustem_test_model_exists
;
; PURPOSE:
; Test if DustEMWrap user has entered a string that matches a known dust model
;
; CATEGORY:
; DustEMWrap, Distributed, Low-Level, helper parse I/O
;
; CALLING SEQUENCE:
; exist_status=dustem_test_model_exists(model)
;
; INPUTS:
; model : string provided by user to indicate an ISM dust model
;
; OPTIONAL INPUT PARAMETERS:
; None
;
; OUTPUTS:
; exist_status : 1 = exists, 0 = does not exists
;
; OPTIONAL OUTPUT PARAMETERS:
;
; ACCEPTED KEY-WORDS:
; help = print this help
; silent = determine status, but don't print anything
; polarisation = check if model includes polarisation
;
; COMMON BLOCKS:
; None
;
; SIDE EFFECTS:
; If model is unknown, code will stop.
;
; RESTRICTIONS:
; The DustEMWrap IDL code must be installed
;
; PROCEDURES AND SUBROUTINES USED:
;
; EXAMPLES
; dustem_test_model_exists,'DL01'
; dustem_test_model_exists,'G17_MODELA',/pol,/silent
