Silvermine Chai Strictly Equal Plugin

What is it?

A plugin for the Chai Assertion Library that adds a .strictlyEqual
method, and disables the .equal method.

Because the difference in .eql (deep equality) and .equal (strict equality) is way too
subtle. Chai provides .deep modifier that modifies .equal to be a deep equality check
(as if it were .eql), further complicating the matter. It would be nice if there were a
.strictly modifier so that you could do .to.strictly.eql(foo), but that doesn't exist,
and would be more difficult to add. So, for any Silvermine codebases where we are using
chai, we will use this plugin and prohibit the use of .equal, replacing it with
.strictlyEqual to be more easily readable - especially for developers not familiar with
our codebase.

How do I use it?

``js
var chai = require('chai');

chai.use(require('@silvermine/chai-strictly-equal'));
`

Or, if you are using TypeScript:

`typescript
import chai from 'chai';
import enableStrictlyEqual from '@silvermine/chai-strictly-equal';

chai.use(enableStrictlyEqual);
`

That's all there is to it. Then your .equal calls will throw an error, indicating that
you should replace them with .eql or .strictlyEqual`.
