The previous implementation was to pass the `key` as the 2nd parameter in `replace` method and force the user to set the "key" prop in their custom React element. This creates further complexity for the end-user. As a result, use `React.cloneElement` which does the same thing without additional work from the user. `React.cloneElement` takes the React element and merges the "key" prop taken from the array index with the original element's props when applicable. https://facebook.github.io/react/docs/top-level-api.html#react.cloneelement

Continuation of #16
Issue:
The previous fix to mitigate the React unique keys warning was to pass the
keyas the 2nd parameter in thereplacemethod.However, this burdens users with the extra work and responsibility to set the "key" prop on their custom React element.
Enhancement:
The smarter approach done in this pull request was to use React.cloneElement to clone the user's custom React element and merge the key prop for them (when applicable).
