* Added possibility to open and close the numpad programmatically: <code>$(selector).numpad('open')</code> and <code>$(selector).numpad('close')</code>
* Registered the plugin in the npm repository.
* Added support for negative numbers and an appropriate button.
* Added support for fractions and a corresponding decimal button.
* Removed the plus and minus button to save space.
* Fixed changing multiple elements at the same time when the numpad is used for a collection (e.g. table column).

* Added <code>onChange</code> callback and corresponding <code>numpad.change</code> event triggered every time the user changes the value displayed on the keypad.
* Pressing done now triggers a change event on the target input - just like regular keyboard typing would do

* Added support for Bootstrap
* Added Bootstrap demo
