The Grenade component extends the Destructable component to allow an object to be destroyed after the specified Lifespan. When this Lifespan has elapsed the parent Destruction method will be called to do the actual destruction. To start this timer the Initialize method must be called and this method has two parameters: force and torque. These parameters will apply a relative force and torque to the Rigidbody when the Grenade is initialized.
The length of time the Grenade should exist before it destroys itself
