Document Watch

Document is a little module that enables you to do one thing, watch for changes in documents in an atomic way.
It's available through npm:

npm install document-watch

And it's super easy to use:

var watch = require('document-watch');

var doc = {hello:'world', count:0};

var unwatch = watch(doc, function(changes) {
	console.log(changes);
});

doc.hello = 'other world';
doc.count++;
doc.count++;

// on nextTick the following gets printed:

{hello:'other world', count:2}
