/// \brief This component sets the local transform of its owner to known values when the simulation starts.
///
/// This component is meant for use cases where an object may be activated and deactivated over and over.
/// For example due to a state machine switching between different object states by (de-)activating a sub-tree of objects.
///
/// Every time an object becomes active, it may want to start moving again from a fixed location.
/// This component helps with that, by reseting the local transform of its owner to such a fixed location once.
///
/// After that, it does nothing else, until it gets deactivated and reactivated again.
