Your solution is basically OOP with composition used. It is 
enough for convenience, but not enough for speed. Also memory 
allocation for each component looks scary.
Systems simply iterate over a all entities that have given set of 
components.
Check my solution API

I have query maker that iterates over smallest collection and 
gets other components. Full code is here

Here is example of usage (single component used here though)
