* `ReactInstanceMap` maintains a mapping from a public facing stateful
* instance (key) and the internal representation (value). This allows public
* methods to accept the user facing instance as an argument and map them back
* to internal methods.
*
* Note that this module is currently shared and assumed to be stateless.
* If this becomes an actual Map, that will break.
