Associate geval events with a given object.
Adapted from code in Mercury's examples.
$ npm install --save weakmap-event
var WeakmapEvent = require('weakmap-event')
var onClick = WeakmapEvent()
var obj1 = {}
var obj2 = {}
onClick.listen(obj1, function(data) {
assert.equal(data, 'hello')
})
onClick.listen(obj2, function(data) {
assert.equal(data, 'goodbye')
})
onClick.broadcast(obj1, 'hello')
onClick.broadcast(obj2, 'goodbye')Creates a new weak-mapped event interface.
