/**
* ### BDD Style Introduction
*
* The BDD style is exposed through `expect` or `should` interfaces. In both
* scenarios, you chain together natural language assertions.
*
* // expect
* var expect = require('chai').expect;
* expect(foo).to.equal('bar');
*
* // should
* var should = require('chai').should();
* foo.should.equal('bar');
*
* #### Differences
*
* The `expect` interface provides a function as a starting point for chaining
* your language assertions. It works on both node.js and in the browser.
*
* The `should` interface extends `Object.prototype` to provide a single getter as
* the starting point for your language assertions. Most browser don't like
* extensions to `Object.prototype` so it is not recommended for browser use.
