This example code is for blessing devices in a factory using a factory blinkup fixture.

For this example:
 - the factory blinkup fixture is a factory imp in an April board mounted on an enclosure with an LED on pin9 and a button on pin8. When the button is pressed it triggers the LED to flash factory BlinkUp code
 - the example device receiving factory BlinkUp is an April board with a button on pin8 and imp card. If the button is pressed within 10 seconds, the device testing is marked as "pass" and the blessing proceeds. If the button is not pressed the device is marked us failed and therefore not blessed.
 - the LED on the device's imp card (not the factory blinkup fixure) will turn solid green indicating pass/bless or turn solid red indicating fail/no blessing
