Write a program TemperatureConverter that extends ConsoleProgram. The program begins by asking the user whether to convert Celsius to Fahrenheit (in which case the user needs to enter a 1) or Fahrenheit to Celcius (in which case the user needs to enter a 2). The program then asks for the temperature and outputs the converted temperature. This is repeated until the sentinel aborts the loop. In our case, a temperature of -1337 acts as a sentinel value.

Here is a sample run of what this should look like:

What do you want me to do?
(1) Convert Celsius to Fahrenheit
(2) Convert Fahrenheit to Celsius
Mode: 2
Temperature: 41
5.0
Temperature: 32
0.0
Temperature: -1337
Goodbye!
