Add the start of a Map from ES7

Like Set, for the time being, this is baseed on top of ArrayObject: two
of them, one for keys, one for values. Again, this goes against the
spirit of the spec (which requires nonlinear access), but having the API
present is at least a start, and the implementation is easily changed.
