/**
Synthetic event that fires when the `value` property of an `<input>` or
`<textarea>` node changes as a result of a user-initiated keystroke, mouse
operation, or input method editor (IME) input event.

Unlike the `onchange` event, this event fires when the value actually changes
and not when the element loses focus. This event also reports IME and
multi-stroke input more reliably than `oninput` or the various key events across
browsers.

For performance reasons, only focused nodes are monitored for changes, so
programmatic value changes on nodes that don't have focus won't be detected.

@example

    YUI().use('event-valuechange', function (Y) {
        Y.one('#my-input').on('valuechange', function (e) {
        });
    });
