;parameters
; wvl [INPUT; required] wavelengths of lines
; flux [INPUT; optional] fluxes of lines
;
;keywords
; Z [INPUT] atomic number of element producing WVL
; ion [INPUT] ionic state of element producing WVL
; * Z and ION do not have to match the size of WVL:
; as many are used as available or necessary
; spec [INPUT] spectrum over which to plot the lines
; lambda [INPUT] as in SPEC(LAMBDA)
; * SPEC and LAMBDA should match in size, or else they
; are both ignored
; order [INPUT] string of comma-separated integers denoting
; grating orders to include in plot
; * default is to use just the first order
; * anything meaningless (including "0") defaults to first order
; wmark [INPUT] additional locations to mark (the output of SMUDGE,
; for example)
; fmark [INPUT] fluxes at which to mark WMARKs
; lmark [INPUT] labels for WMARKs
; * FMARK and LMARK are ignored unless they match WMARK
; cmark [INPUT] colors for LMARKs
; markc [INPUT] colors for WVLs
; * default is 222
; xo [OUTPUT] output from PICKRANGE
; yo [OUTPUT] output from PICKRANGE
; oxr [OUTPUT] output from PICKRANGE
; oyr [OUTPUT] output from PICKRANGE
; _extra [INPUT] pass defined keywords to subroutines:-
; STR_2_ARR: SEP,SQUISH
; PICKRANGE: DYNRNG,MARKP,MARKS,MARKO,QUIET,XTITLE,YTITLE,TITLE
