[GUI] display information state of an agent

Visualize information state of an agent in the GUI (Online-Visualization + Post-Vis.)

Agents can receive different types of information, e.g.

• In the default setting, we assume agents have global knowledge about the location to target (NO_INFORMATION).
• If the psychology layer is used, the information is set up as a stimulus.
• If the crowd is managed e.g. over TraCI, information can be passed as directly to an agent or as stimuli.
• If the reaction behavior is modeled, it is also possible that agents refuse to react to information (INFORMATION_UNCONVINCING_RECEIVED).

For that purpose, I have added the enum InformationState.class

public enum InformationState {
    NO_INFORMATION,
    INFORMATION_STIMULUS,
    INFORMATION_RECEIVED,
    INFORMATION_CONVINCING_RECEIVED,
    INFORMATION_UNCONVINCING_RECEIVED,
}

The default value is NO_INFORMATION.

What is new?

The user can pick a new option for agent coloring 'Coloring by Information State', see following image:

New feature: Visualize CHANGE_TARGET and WAIT behavior

Currently, the two stimuli ChangeTarget and Wait are not being visualized in the post-visualization.

The reason is that these two stimuli happen in between two footsteps. Therefore, the stimuli are not written out by the respective dataprocessors

• FootStepMostImportantStimulusProcessor
• FootStepPsychologyStatusProcessor -> its output file is used in the postvis!
• FootStepSelfCategoryProcessor

Example output file FootStepPsychologyStatusProcessor

In the output file cannot see the WAIT stimuli that starts at t=0.0s and lasts until t=10.0s.

I propose, that in case of stimuli that are active in between footsteps (CHANGE_TARGET and WAIT), the stimuli should be mapped to the last available time step.

In this case, the output file looks like:
