Namespaced global event emitter
## Usage
Sparkles exports a function that returns a singleton `EventEmitter`.
This EE can be shared across your application, whether or not node loads
multiple copies.
```js
var sparkles = require('sparkles')(); // make sure to call the function
sparkles.on('my-event', function(evt){
console.log('my-event handled', evt);
});
sparkles.emit('my-event', { my: 'event' });
```
## API
### sparkles(namespace)
Returns an EventEmitter that is shared amongst the provided namespace. If no namespace
is provided, returns a default EventEmitter.
### sparkles.exists(namespace);
Checks whether a namespace exists and returns true or false.
## Why the name?
This is a "global emitter"; shortened: "glitter" but it was already taken; so we got sparkles instead :smile:
