var hc = hasChanged(input)
Pass in an input[type=text|password|email...]
element. A keyup
handler
will be bound to it and filter out nav keys like arrows and tabbing.
hc#changed
Emitted if the val on keyup is different than the original value.
hc#original
Emitter if the val on key is the same as the original value.
hc.update(val)
Update the original value. This makes it easy to change behavior without worrying about rebinding events.
