// Alot of the time it will be sensible to have the same object/component implementing both the characters perception management (awareness state)
// and the perception event invoker, because the thing managing what the character is aware of is the best position to know when to invoke certain
// events relating to those very perceptions. However, those things are still logically distinct in regard to the USERS of those operations, namely,
// some clients will care about controlling the parameters of the awareness logic, while others will only care about recieving updates on what the
// character is currently awareof/percieving. Consequently, these are two distinct interfaces!
// Use unity engine to aquire all the dependencies needed for a character to operate. They are mandated by this script to be attached to the gameobject.
