An inefficient, but as W3C-compliant as possible using only pure JavaScript, DOMStorage implementation.

Purpose
----

This is meant for the purpose of being able to run unit-tests and such for browser-y modules in node.

Usage
----

``javascript
var Storage = require('dom-storage');

// in-file, doesn't call String(val) on values (default)
var localStorage = new Storage('./db.json', { strict: false, ws: ' ' });

// in-memory, does call String(val) on values (i.e. {} becomes '[object Object]'
var sessionStorage = new Storage(null, { strict: true });

var myValue = { foo: 'bar', baz: 'quux' };

localStorage.setItem('myKey', myValue);
myValue = localStorage.getItem('myKey');

// use JSON to stringify / parse when using strict w3c compliance
sessionStorage.setItem('myKey', JSON.stringify(myValue));
myValue = JSON.parse(localStorage.getItem('myKey'));
`

API
---

* getItem(key)
* setItem(key, value)
* removeItem(key)
* clear()
* key(n)
* length

$3

* strict - whether to stringify strictly as text [Object object] or as json { foo: bar }.
* ws - the whitespace to use saving json to disk. Defaults to ' '.

Tests
---

`javascript
0 === localStorage.length;
null === localStorage.getItem('doesn\'t exist');
undefined === localStorage['doesn\'t exist'];

localStorage.setItem('myItem');
'undefined' === localStorage.getItem('myItem');
1 === localStorage.length;

localStorage.setItem('myItem', 0);
'0' === localStorage.getItem('myItem');

localStorage.removeItem('myItem', 0);
0 === localStorage.length;

localStorage.clear();
0 === localStorage.length;
`

Notes
---

* db is read in synchronously
* No callback when db is saved
* Doesn't not emit Storage` events (not sure how to do)
