 *   DESC: Model for ADC values.
 *
 *   This file declares the interface used by TOSSIM for adc (sensor)
 *   simulation.
 *
 *   A data pointer is provided so that large structures can be
 *   dynamically allocated. Otherwise, the simulation has to allocate
 *   the regions of memory for every model, even though only one is in use.
