*
* Driver for the Zoul user button
*
* The user button (on Zoul-based platforms like the RE-Mote and the Firefly)
* will generate a sensors_changed event on press as well as on release.
*
* Unlike many other platforms, the user button has the ability to
* generate events when the user keeps the button pressed. The user can
* configure the button driver with a timer interval in clock ticks. When the
* button is kept pressed, the driver will then generate a broadcast event
* each time the interval passes. For example the driver can be configured to
* generate an event every second while the button is kept pressed. This
* functionality can be enabled through the configure() function, by passing
* BUTTON_SENSOR_CONFIG_TYPE_INTERVAL as the type argument.
