A JavaScript implementation to allow expressions such as 3 > 2 > 1

greaterThan.js

/**
 * This basically allows expressions like 3 > 2 > 1 
 * which is usually written as 3 > 2 && 2 > 1
 *
 * I basically did this because I wanted to see how easy it is 
 * to implement such "new syntax" in JS
 *
 * Please don't use this. It's hacky.
