Function getByPath

getByPath<T>(path, node, options?): Entry

   *    street: 'West St',
   *    city: 'Blahville'
  },
colour: 'red'
 *  }
}
Trees.getByPath('jane.address.postcode', people); // '.' default separator
// ['postcode', 1000]
Trees.getByPath('jane.address.country.state', people);
// ['country', undefined] - since full path could not be resolved.
