Unfortunately, ReactJS did not export an easy way to check if something is a ReactElement, although they do so in the internal code with REACT_ELEMENT_TYPE.

This function is required when receiving ReactElement from javascript (eg in a callback) or to interface with foreign React Elements.

React only allows a single top most element. Provide a handly function to wrap a list of ReactElements inside a div if required. If there is only one element in the list, then nothing is changed.
