What is IsSensor?

Sorry, I'm kidda noob in Farseer and would like to ask what does IsSensor do?

Is a geometry that has no collision reaction at all (doesn't collide with anything), but you still can check when something contacts it. Useful for.. sensors for example. When your character reachs a specific area you can trigger an action, you can check that the character reached the area by using a sensor.

Correct me if I'm wrong, but if a list of contacts are still made, doesn't that mean that it is still a part of the collision system, and therefore a part of any overhead in building the collision trees?

Contacts are created and the sensor is included in the whole collision system (It is quite effective), but the contacts created with the sensor is not included in the collision response system.
