Helper class for creating pools of objects. An example use looks like this:

class MyPooledClass {

    fun recycle() {
        // Clear state if needed, then return this instance to the Pool
        pool.release(this)
    }

    companion object {
        private val pool = Pools.SynchronizedPool<MyPooledClass>(10)

        fun obtain() : MyPooledClass {
            // Get an instance from the Pool or
            // construct a new one if none are available
            return pool.acquire() ?: MyPooledClass()
        }
    }
}
