Arduino compatibility example

This example shows that it is now possible to re-use arduino sketches in Contiki. This example documents the necessary magic. Arduino specifies two routines, setup and loop. Before setup is called, the framework initializes hardware. In original Arduino, all this is done in a main function (in C). For contiki we define a process that does the same.

See the documentation file in apps/contiki-compat/README.md

We use the Serial1 Port to write the Tag Info out We use the SPI Bus to connect the RFID reader to the merkurboard https://github.com/miguelbalboa/rfid
