The ChillMapper class is a main class that displays wind chill values on a map (of Virginia).

OR-1 As with all main classes, the main() method must be passed a String[] containing the command-line arguments.

OR-2 If there are no command-line arguments, the system must display a map containing wind chill values calculated from the weather data in the file named "today.txt".

OR-3 If there is one command-line arguments, the system must display a map containing wind chill values calculated from the weather data in the file with the name contained in that argument (e.g., "yesterday.txt").

OR-4 If there are 3, 6, 9, etc... command line arguments (i.e., if the number of command line arguments is a multiple of 3) then the system must display a map containing the wind chill values calculated from the weather data contained in the arguments.

OR-5 In all other cases, the system must not display a map.

OR-6 If either the temperature or the wind speed can't be converted into a valid double value for a particular station, that station must be ignored (but others must be processed).

OR-7 Regardless of the source of the weather data (i.e., whether it is in a file or the command-line arguments), the system must use the first value as a String representation of the ICAO code, the second value as a String representation of the temperature (in degrees Farenheit), and the third value as a String representation of the wind speed (in mi/hr).

OR-8 The main class must use the windChillNA() function in the Weather class to calculate the wind chill values.

OR-9 The main class must use the setTemperature() function in the Map class to display the temperatures on the map.

OR-10 The system must calculate and display the wind chill values for every station in the file or every station in the command-line arguments (depending on how the application is started). In the case of the former, there will be as many stations as there are lines in the file. In the case of the latter, there will be as many stations as there are command-line arguments divided by three.
