Implement a custom field algebra class.

See code here

var Boole = require('./Boole')

console.log(Boole.contains(true)); // true
console.log(Boole.contains(10)); // false

console.log(Boole.addition(true, false)); // false
console.log(Boole.addition(true, true)); // true
console.log(Boole.addition(false, false)); // false
