Some devices compute the number of calories that the user has burnt since the last reset.
One of this devices is Freescale's MMA9553L (http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf) that computes the number of calories based on weight and step rate. Introduce a new channel type CALORIES to export these values.
