## Description

plotoccupation creates multiple subplots, one for each diagonal element of the density matrix. Subplot titles are automatically generated and can be found in the statenames variable of the system class. If i is provided only the i-th element is plottet.

## Example: Qbit in a cavity

    clear; close all;
    s = System;
    a = Nlevel(1);
    s.addEntity(a,'qbit');
    s.addEntity(Qoscillator(3,1),'cavity');
    s.addCoupling('qbit','cavity',0.05);
    s.addDissipation('qbit',200);
    s.addExternalField(Gausspulse(0.04,100,30,1),'qbit');
    s.setTmax(400);
    s.setTimestep(0.1);
    s.simulate;

    figure('units','normalized','outerposition',[0 0 1 1]) %make full screen figure
