NAME: tdpwrspc PURPOSE: wapper for dpwrspc.pro allowing input of a tplot variable name CALLING SEQUENCE: tdpwrspc, varname, newname=newname,_extra=_extra INPUT: varname = one tplot variable name KEYWORDS: newname = if set,give this name to the new data, the default is to append '_dpwrspc' to the input name and pass out the name in the newname variable, Unless /overwrite is set.
