Usage

'use strict'

var k = require('kontrak')

console.log('' + k.contracts.string('hello')) // Yay!
console.log('' + k.contracts.string(10)) // Whoops!
console.log('' + k.contracts.number(10)) // Yay!
console.log('' + k.contracts.number('wat')) // DO YOU THINK I'M STUPID?!?
console.log('' + k.contracts.number(NaN)) // Fuck you, JavaScript. But yay!
console.log('' + k.maybe(k.contracts.string)(k.maybe.nothing())) // > Nothing
console.log('' + k.m(k.c.string)(k.m.nothing())) // > Nothing
console.log('' + k.maybe(k.contracts.string)(k.maybe.just('hello'))) // > Just(hello)
