; Name        : SAVE_ANALYSIS
;               
; Purpose     : Save a CFIT ANALYSIS structure with data
;               
; Explanation : Saves all the data associated with a CFIT ANALYSIS structure,
;               retrievable by RESTORE_ANALYSIS.
;               
; Use         : SAVE_ANALYSIS,ANALYSIS
;    
; Inputs      : ANALYSIS : Component fitting system (CFIT) analysis structure,
;                          containing the data to be saved, and the file name
;                          to be used when saving. If no file name is given, 
;                          pickfile will be used to prompt for one.
;                          
; Opt. Inputs : None.
;               
; Outputs     : None.
;               
; Opt. Outputs: None.
;               
; Keywords    : VERBOSE : Propagated to the SAVE command.
;
; Calls       : bigpickfile, break_file, default, datatype()
;
; Common      : None.
;               
; Restrictions: Must have widgets to use pickfile.
;               
; Side effects: None.
;               
; Category    : Line fitting.
;               
; Prev. Hist. : None.
