clustering evac and room exit weights bug

[AleksanderKamienski]

Error in combining the agent clustering functionality and door weight functionality. It happens that followers pass through the door in front of the leader and then are assigned a goal similar to the leader (the door they have just passed through) - this causes the agents to push, some in one direction of the door, others in the other.

Below I added the cad.json and conf.json file for the scenario for which this occurred. For navmesh debugging purposes, evac/config.json.DETECTION_TIME parameter was set to 0.

Proposition from today's meeting: we can add a switch that turns off leader following feature.

Hence, there will be two modes of grouping algorithm:

1. Default - agents are clustered, same pre-evac time within cluster, all agents follow near-centroid leader (goal on leader's next door).
2. Modified - agents are clustered, same pre-evac time within cluster, each agent heads to the final exit.

Changes required:

• checkbox in advanced form with label like "leader following"
• condition in evac.worker where all agents are flagged as leaders if leader-following feature is disabled
