;NAME:
; tpwrspc
;PURPOSE:
; wapper for pwrspc.pro for calling from GUI, a split_vec is performed
; on the data if necessary
;CALLING SEQUENCE:
; thm_ui_pwrspc, varnames, new_names, trange, history_ext, $
;                polar = polar, dynamic = dynamic, _extra = _extra
;INPUT:
; varnames = an array (or scalar) of tplot variable names
;Output
; new_names = the variable names of any new variables
;HISTORY:
; 28-mar-2007, jmm, jimm.ssl.berkeley.edu
; 2-apr-2007, jmm, added the /dynamic keyword
; 5-jun-2007, jmm, no longer handles history
