; @file_comments write an idl procedure, compile it and execute it.
;
; @param command {in}{required} a string array defining the procedure to be created. each element will be a line of the created procedure. 
;
; @keyword FILENAMEIN name of the procedure to be created.
;      'for_createpro.pro' by default
;
; @keyword KWDLIST a vector string. to specify a list of keywords that
;      must be included in the procedure definition. Warning: the string
;      must start with a ',' for example: KWDLIST = ', TOTO = toto'
;
; @keyword _EXTRA used to pass your keywords to the created procedure.
;
; SIDE EFFECTS: ends the procedure name with '.pro' if needed
;
; @restrictions is not working with functions, use createfunc instead.
;              arguments can be given only through keywords
;
