attachComponent
template<class CT, typename ...Params>
CT &attachComponent(GameObject &parent, Params &&... params) const noexcept;

Attaches a new component of type CT to parent, creating it with params as constructor parameters.

detachComponent
void detachComponent(GameObject &go, const IComponent &comp) const;

Removes comp from go.

getParent
const GameObject &getParent(const IComponent &comp) const;

Returns the GameObject to which comp is attached.

getGameObjects
template<typename T>
const std::vector<GameObject *> &getGameObjects();

Returns all the GameObjects with a T attached to them. This is the main way for Systems to access GameObjects. The results for this function are pre-calculated, and its runtime cost is minimal.
