; res=dustem_greybody_mpfit(x,params[,_EXTRA=extra][,cc_sed=cc_sed][,/help])
; INPUTS:
; x = necessary for interface but unused
; params = Model parameters normalized to initial values ([amplitude,T,beta])
; OPTIONAL INPUT PARAMETERS:
; cc_sed = SED color correction factors
; _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 if !dustem_show_plot
; RESTRICTIONS:
; The dustem idl wrapper must be installed
; PROCEDURE:
; None
