    Author: csmit195
    Server: Toasty Networks - Tekkit Legends

    For usage by: namar4777
    Description: Script remotely controls Reactor via Pocket Computer regardless of distance using HTTP Post API. The code relies on regularily checking for status updates.

    Technologies used:
    * Lua / ComputerCraft
    * NodeJS DataStore server(offering as a free service)

    Potential Future Upgrades:
    Remote mobile / web app controller as long as reactor is chunk loaded.
