Program name: Lolmer's EZ-NUKE reactor control system

Programmer: Lolmer

Description:
This program controls a Big Reactors nuclear reactor in Minecraft with a Computercraft computer, using Computercraft's own wired modem connected to the reactors computer control port.
These scripts are known to run on:
- Minecraft 1.6.4
        - NST Diet (https://www.technicpack.net/modpack/never-stop-toasting-diet.254882)
        - NST Maxx (https://www.technicpack.net/modpack/nstmaxx.398172)
- Minecraft 1.7.10
        - FTB Infinity (http://www.feed-the-beast.com/modpacks/FTBInfinity)
        - Modderation: Permabanned (https://www.technicpack.net/modpack/modderation-permabanned-edition.449941)
        - Modderation: FYAD (https://www.technicpack.net/modpack/modderation-fyad-edition.696257)
- Minecraft 1.12:
        - All the Mods 3 (https://minecraft.curseforge.com/projects/all-the-mods-3)
To simplify the code and guesswork, I assume the following monitor layout, where each "monitor" listed below is a collection of three wide by two high Advanced Monitors:
1) One Advanced Monitor for overall status display plus
	one or more Reactors plus
	none or more Turbines.
2) One Advanced Monitor for overall status display plus (furthest monitor from computer by cable length)
	one Advanced Monitor for each connected Reactor plus (subsequent found monitors)
	one Advanced Monitor for each connected Turbine (last group of monitors found).
If you enable debug mode, add one additional Advanced Monitor for #1 or #2.
Notes
----------------------------
- Only one reactor and one, two, and three turbines have been tested with the above, but IN THEORY any number is supported.
- Devices are found in the reverse order they are plugged in, so monitor_10 will be found before monitor_9.
When using actively cooled reactors with turbines, keep the following in mind:
- 1 mB steam carries up to 10RF of potential energy to extract in a turbine.
- Actively cooled reactors produce steam, not power.
- You will need about 10 mB of water for each 1 mB of steam that you want to create in a 7^3 reactor.
- Two 15x15x14 Turbines can output 260K RF/t by just one 7^3 (four rods) reactor putting out 4k mB steam.
Features
----------------------------
- Configurable min/max energy buffer and min/max temperature via ReactorOptions file.
- Disengages coils and minimizes flow for turbines over max energy buffer.
- ReactorOptions is read on start and then current values are saved every program cycle.
- Rod Control value in ReactorOptions is only useful for initial start, after that the program saves the current Rod Control average over all Fuel Rods for next boot.
- Auto-adjusts control rods per reactor to maintain temperature.
- Will display reactor data to all attached monitors of correct dimensions.
	- For multiple monitors, the first monitor (often last plugged in) is the overall status monitor.
- For multiple monitors, the first monitor (often last plugged in) is the overall status monitor.
- A new cruise mode from mechaet, ONLINE will be "blue" when active, to keep your actively cooled reactors running smoothly.
GUI Usage
----------------------------
- Right-clicking between "< * >" of the last row of a monitor alternates the device selection between Reactor, Turbine, and Status output.
	- Right-clicking "<" and ">" switches between connected devices, starting with the currently selected type, but not limited to them.
- The other "<" and ">" buttons, when right-clicked with the mouse, will decrease and increase, respectively, the values assigned to the monitor:
	- "Rod (%)" will lower/raise the Reactor Control Rods for that Reactor
	- "mB/t" will lower/raise the Turbine Flow Rate maximum for that Turbine
	- "RPM" will lower/raise the target Turbine RPM for that Turbine
- Right-clicking between the "<" and ">" (not on them) will disable auto-adjust of that value for attached device.
	- Right-clicking on the "Enabled" or "Disabled" text for auto-adjust will do the same.
- Right-clicking on "ONLINE" or "OFFLINE" at the top-right will toggle the state of attached device.
Default values
----------------------------
- Rod Control: 90% (Let's start off safe and then power up as we can)
- Minimum Energy Buffer: 15% (will power on below this value)
- Maximum Energy Buffer: 85% (will power off above this value)
- Minimum Passive Cooling Temperature: 950^C (will raise control rods below this value)
- Maximum Passive Cooling Temperature: 1,400^C (will lower control rods above this value)
- Minimum Active Cooling Temperature: 300^C (will raise the control rods below this value)
- Maximum Active Cooling Temperature: 420^C (will lower control rods above this value)
- Optimal Turbine RPM:  900, 1,800, or 2,700 (divisible by 900)
	- New user-controlled option for target speed of turbines, defaults to 2726RPM, which is high-optimal.
Requirements
----------------------------
- Advanced Monitor size is X: 29, Y: 12 with a 3x2 size
- Computer or Advanced Computer
- Modems (not wireless) connecting each of the Computer to both the Advanced Monitor and Reactor Computer Port.
- Big Reactors (http://www.big-reactors.com/) 0.3.2A+ or Extreme Reactors (https://minecraft.curseforge.com/projects/extreme-reactors)
- Computercraft (http://computercraft.info/) 1.58, 1.63+, 1.73+, or 1.80pr1+
- Reset the computer any time number of connected devices change.
