 *   DESC: Model for RF connectivity.
 *
 *   This file declares the interface used by TOSSIM for radio simulation.
 *   There are currently three implementations of this interface:
 *   simple, static, and space. Simple and static are defined in rfm_model.c,
 *   while space is defined in its own file.
 *
 *   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.
