Added:

    generate_route_list(route_str):
    generate_route_string(route_list): - refactored route_helper to call this function, also used for server.

    def load_initial_json(prompt=True):
        """Refactored initial prompt for query to this helper function"""


Fixed:
    json_api_request(graph, code): - Now handles exception when a city is not found from the API request
    Fixed setting routes properly when editing a city's code.

Refactoring:
    Refactored functions in CSAir.py to return a string instead of printing.
    Refactored loops to use enumerate

    @todo log other functions refactored.
