report temperature.py

# this is an example method from the Librarian ChatBot class
#   note that this is a simple example with a few hard coded imagenode names

    def report_temperature(self, locations):
        """ report temperature by location

        This is a very awkward test matching of location and temperature.
        Needs to be made much more sophistcated than if / else / etc.

        Parameters:
          locations (set): location words (each a str)

        Returns:
          reply (str): Sentences reporting temperatures for all the locations.
