; NAME:
; dustem_plot_fit_sed
; PURPOSE:
; Plots a Dustem model and SED. Parameter values and error are
; printed on plot. Used for plotting results during fit.
; CATEGORY:
; Dustem
; CALLING SEQUENCE:
; dustem_plot_fit_sed,st,sed,cont[,/no_spec_error][,res=][,errors=][,chi2=][,rchi2=][/help][_extra=]
; INPUTS:
; st = Dustem model output structure
; sed = Dustem model SED
; cont = Dustem model NIR continuum
; OPTIONAL INPUT PARAMETERS:
; res = fit result values. If set values are written on plot.
; errors = fit result errors. If set values are written on plot.
; chi2 = fit chi^2. if set value is written on plot.
; rchi2 = Reduced fit chi^2. if set value is written on plot.
; _extra = extra parameters for the plot routine
; OUTPUTS:
; None
; OPTIONAL OUTPUT PARAMETERS:
; None
; ACCEPTED KEY-WORDS:
; help = If set, print this help
; COMMON BLOCKS:
; None
; SIDE EFFECTS:
; SED and model are plotted
; RESTRICTIONS:
; The dustem idl wrapper must be installed
; PROCEDURE:
; None
; EXAMPLES
