    Returns the nightly's forecast for a given city.
    Inputs:
    city (string): A valid string
    Output:
    period (dictionary/JSON): a dictionary containing at least, the forecast keys startTime, endTime and detailedForecast.
    Throws:
    CityNotFoundError if geopy returns empty list or if the latitude longitude fields are empty.
    ForecastUnavailable if the period is empty or the API throws any status code that is not 200
    Hint:
    * Return the period that is labeled as "Tonight"
