;NAME:
; tdeflag
;PURPOSE:
; wapper for xdeflag.pro allowing input of tplot variable names
;CALLING SEQUENCE:
; tdeflag, varnames, method, newname=newname, $
;          overwrite = overwrite, _extra=_extra
;INPUT:
; varnames = an array (or scalar) of tplot variable names
; method = set to "repeat", this will repeat the last good value.
;          set to "linear", then linear interpolation is used, but for
;          the edges, the closest value is used, there is no
;          extrapolation
;KEYWORDS:
; flag = the value that deflagged data will be set to, the default is
;        6.8792e28, Nan's, Inf's are also deflagged
; maxgap = the maximum number of rows that can be filled? the default
;           is n_elements(t)
; newname = if set,give these names to the deflagged data, the
;                default is to append '_deflag' to the input names and
;                pass out the names in the newname variables,
;                Unless /overwrite is set
; overwrite = if set, write the new data back to the old tplot
;             variables, do not set this with newname
