; NAME:
;    dustem_set_data
; PURPOSE:
;    Initializes the dustem data structure (*!dustem_data) used in the fitting
;    Initializes the !dustem_show structure which is either a copy or a more detailed version of !dustem_data 
; CATEGORY:
;    DustEMWrap, Mid-Level, Distributed, Initialization
; CALLING SEQUENCE:
;    dustem_set_data[,m_fit,x_fit][,m_show,x_show][,rchi2_weight=][,f_HI=][,/help]
; INPUTS:
;    None
; OPTIONAL INPUT PARAMETERS:
;    m_fit : dustemwrap structure contaning emission data to be fitted 
;    x_fit : dustemwrap structure containing extinction data to be fitted
;    m_show : dustemwrap structure containing emission data to be displayed
;    x_show : dustemwrap structure containing extinctiond data to be displayed
;    rchi2_weight : dustemwrap structure containing the wieghts for chi2 calculation
;    f_HI : multiplicative factor for the SED values (extinction and emission)
; OUTPUTS:
;    None
; OPTIONAL OUTPUT PARAMETERS:
;    None
; ACCEPTED KEY-WORDS:
;    help      = If set print this help
; COMMON BLOCKS:
;    None
; SIDE EFFECTS:
;    initializes !dustem_data and !dustem_show
;    wavelengths are forced to be the central filter wavelength for photometric data
; RESTRICTIONS:
;    The dustem idl wrapper must be installed
; PROCEDURE:
;    None
; EXAMPLES
;    dustem_init
;    dir=!dustem_wrap_soft_dir+'/Data/EXAMPLE_OBSDATA/'
;    file=dir+'example_SED_1.xcat'
;    spec=read_xcat(file,/silent)
;    dustem_set_data,spec,x_fit,spec,x_show)
;    #in this example !dustem_data and !dustem_show are identical
; MODIFICATION HISTORY:
;    Written by J.-Ph. Bernard 2007
;    V. Guillet (2012) : dustem_set_data is turned into a function which can be used 
;                        indifferently for sed, ext, polext
;    I. Choubani (2022): dustem_check_data is introduced and the data structure format of the latest release is respected.
;                       dustem_set_data is turned into a procedure.
;    Evolution details on the DustEMWrap gitlab.
;    See http://dustemwrap.irap.omp.eu/ for FAQ and help.

;To me this is unnecessary... as dustem_check_data is always needed as it shapes the output structures (that would otherwise not exist)
;in order to prepare them for the mpfit run.
