New Features

• Deep-merge tracking data (#14) We now do a deep-merge of the tracking data. Previously we were doing a shallow-merge which meant that tracking data that shared a subkey would "lose" to the deepest version.
• Exporting TrackingPropTypes (#18) you can now import the PropTypes definition for the tracking context object, if needed.
• options.dispatchOnMount (#16) The "auto-dispatch" behavior is now opt-in. See Breaking Changes below for more info.

Breaking Changes

We no longer "auto-dispatch" when seeing tracking data like { page: 'FooPage' }. Instead you can opt-in to auto-dispatching by passing in options.dispatchOnMount, which will dispatch the tracking data when the component mounts. Like so:

@track({ page: 'FooPage' }, { dispatchOnMount: true })
export default class FooPage extends Component { ... }

This also means the previous behavior of automatically including { event: 'pageDataReady' } is no longer the case, and if this needs to be part of your tracking data you will have to manually include it where necessary.

See the README for more info.
