Serialize/deserialize json and conserve typed arrays

	/*
	Author: Jonathan Lurie - http://me.jonathanlurie.fr
	License: MIT

	The point of this little gist is to fix the issue of losing
	typed arrays when calling the default JSON serilization.
	The default mode has for effect to convert typed arrays into
	object like that: {0: 0.1, 1: 0.2, 2: 0.3} what used to be
	Float32Array([0.1, 0.2, 0.3]) and once it takes the shape of an
	object, there is no way to get it back in an automated way!

Get host machine endianness using JavaScript Typed Arrays (polyfill for `os.endianness()` in node.js)

	function endianness () {
	var b = new ArrayBuffer(4);
	var a = new Uint32Array(b);
	var c = new Uint8Array(b);
	a[0] = 0xdeadbeef;
	if (c[0] == 0xef) return 'LE';
	if (c[0] == 0xde) return 'BE';
	throw new Error('unknown endianness');
	}
