* Copies stuff.
*
* If destination is not provided and source is an object or an array, a copy is created & returned,
* otherwise the source is returned.
*
* If destination is provided, all of its properties will be deleted and if source is an object or
* an array, all of its members will be copied into the destination object. Finally the destination
* is returned just for kicks.
*
* @param {*} source The source to be used during copy.
* Can be any type including primitives, null and undefined.
* @param {(Object|Array)=} destination Optional destination into which the source is copied
* @return {*}
