###### Airsoft/Paintball Domination Game ######

Description:

No space for the batteries, so that was a bad design.  Everything but the 6 LED lamps is powered
by a 5v USB battery bank.  The LED lamps are powered by an airsoft 11.1v lipo.

To start a game, just press and release the "admin" button (the yellow/orange middle one that
doesn't illuminate.  That immediately begins starts the game timer (which can be changed in the code).
The box blinks orange to indicate no team has held the point yet.

Blue team presses and releases the blue button and their time begins immediately, complete
with the blue flashing light.  Green button does the same.  

When the game timer runs out, the program looks at the two accrued times, and whichever
team has the most time, the box will rapidly blink that team's color LED lamps.

In the case of a tie, the box will rapidly blink the orange admin lights.  And, of course,


    The circuit:

      Arduino Uno R3.
      SunFounder IIC I2C 16x2.
      3 momentary push buttons (two illuminate).
      Three relays.
      Six LED lamps in appropriate colors.
      Translucent ammo can.
