Get Input with InputReceiver Class

[FosterSamuel]

The InputReceiver class should offer a static int method, getOptionFromChoices(String[] menu). This method will output a list of the menu, handle user input within the bounds of the options and return the inputted choice.

For example, passing ["See all reminders", "Toggle reminder", "Create reminder", "Delete reminder"] will output the list:

1. See all reminders
2. Toggle reminder
3. Create reminder
4. Delete reminder

For that input, it will ignore input outside of the choices 1, 2, 3 or 4.

This class will be used inside of SanteMenu. See #46.
