Add a date parsing user-defined callback demo

This Minor release includes the implementation of a new user demo that features a more complex (ie date) user-defined callback.

Re-implemented all examples/demos

This patch update addresses the previously poor state of demos. There was a mix of SPA (Single Page App) like UI, with standalone/unstyled UI. In addition the code in the demos was hard to follow for users.

To address this, a new simpler template will be used for all demos. The template will contain code that is as minimal and straight-forward to follow as possible, and styled to look nice as well as work well.

Chages:

• created a new, simpler demo teplate
• converted all existing demos to use the new template
• extracted CSS into an external stylesheet
• added syntax highlighting to the demos

Fix npm `prepublish`

Fix a mistake in the prepublish script to unblock publishing to NPM.
