ref Forwarding in React 16.3

When we create nested components in react, react does not allow accessing the DOM of the inner element through refs, The ref on the wrapper component points to the wrapper component and not the inner component. In some cases we might need to access the inner component through refs, react 16.3 provides a way to achieve this using ref Forwarding.
