Controls all movement related things of a host

ConstSpeedMobility does not use one of the standard mobility approaches. The user can define a velocity for each Host and an update interval. If the velocity is greater than zero (i.e. the Host is not stationary) the ConstSpeedMobility module calculates a random target position for the Host. Every update interval ConstSpeedMobility calculates the new position on its way to the target position and updates the display. Once the target position is reached ConstSpeedMobility calculates a new target position.

This component has been taken over from Mobility Framework 1.0a5.
