Writing modular code using "require"

Excellent! I should be receiving my board next week and in the meantime have been putting together some code - migrating a central heating timer from delphi to javascript - this will be in its own module.

It may be of use to others (for anything that needs triggered regularly and repeats on a weekly cycle) so I will share it (with documentation) when finished.

I find the following site very useful for developing/testing javascript:

http://repl.it/languages/JavaScript

(hopefully the code I have written will run ok on espruino - I'm doing nothing fancy!)
