Spark

Spark.io support
As long as it's in line with an arduino variant (having the correct pin defines, etc) it should be okay to include. Up to this point everything in firmata/arduino has been specific to boards included in the core distribution (well at least included at one time or another... some have been dropped).

Are all of the same basic features as something like an Arduino UNO supported for Spark Core (I2C, analog pins can be set as digital pins, etc) or are exceptions needed - not sure how to handle that.
