NAME: join_vec.pro PURPOSE: Take a series of similar variables and store as a single vector; e.g. one dimensional variables Vp_x, Vp_y, vp_z can be combined to form a three dimensional variable Vp. CALLING SEQUENCE: join_vec, 'thm_state_pos'+['_x','_y','_z'], 'thm_state_pos_new' ARGUMENTS: NAMES: Array of tplot variable names to be joined into single variable NEW_NAME: Single string containing the name of the tplot variable to be created KEYWORDS display_object = Object reference to be passed to dprint for output. NOTES: Meant to compliment split_vec.pro
