function displaytotcurrevol_geom(obj,timesteps,toptitle,scalet,dens,subdiv,nmean, rsplit)
% Computes and display the time evolution of the outgoing
% currents at time obj.t2d(timesteps)
%-scalet=true scales the time by the ellastic collision
% frequency
%- dens = true plot the time evolution of the maximum electron
% density in the simulation domain otherwise plot the total
% number of electrons in the domain
% also plot in a subplot the color coded boundary corresponding
% to each current
% - subdiv allows the subdivision of individual boundaries by
% defining relative length e.g. [1 1] divides the boundary in
% two boundaries of equal length
% - nmean defines the window time average for the current and
% density
% - rsplit defines the radial position, for the calculation of the
% time evolution of the density, at which a new cloud is considered.
% This helps tracking the density in two clouds at the same
% time.
