Add `spy` constructor to ObservableMap (#4)

Sometimes it's useful to observe changes on top of a Map implementation
which has different behavior from one of the built in map types.

- Add a test calling the 'spy' constructor
  Most functionality is already tested. Make sure that calling the 'spy'
  constructor delegates to the underlying map implementation.
