/// Creates a new PrefabPool in this Pool and instances the requested

///
/// It is rare this function is needed during regular usage.
/// This function should only be used if you need to set the preferences
/// of a new PrefabPool, such as culling or pre-loading, before use. Otherwise,
/// just use Spawn() and if the prefab is used for the first time a PrefabPool
/// will automatically be created with defaults anyway.
///
/// Note: Instances with ParticleEmitters can be preloaded too because
/// it won't trigger the emmiter or the coroutine which waits for
/// particles to die, which Spawn() does.
///
/// Usage Example:
/// // Creates a prefab pool and sets culling options but doesn't
/// // need to spawn any instances (this is fine)
/// PrefabPool prefabPool = new PrefabPool()
/// prefabPool.prefab = myPrefabReference;
/// prefabPool.preloadAmount = 0;
/// prefabPool.cullDespawned = True;
/// prefabPool.cullAbove = 50;
/// prefabPool.cullDelay = 30;
///
/// // Enemies is just an example. Any pool is fine.
