Features: auto clean up on set intervals.

Usage: !!!You have to create a class that inherits from AbstractPoolable, and add the component to your poolable gameobject. After that you can proceed.!!!

Init: Awake()=> myPool = new ObjectPool(myObjectToPool, initialElements, useActivePool, autoCleanup, autoCleanUpInterval);

Pool out: OnTriggerEnter()=> myPool.AddObjectAtPosition(enemyPosition);

Pool back:

OnDeath()=> Poolback();

!!! - this is the tricky part from your side; calling it is easy, just got to find the right function, my general advice is not to use OnDisable()!!!
