 *   DESC: A flat address space for LOGGER emulation.
 *
 * Anonymous EEPROMs are not kept between simulator invocations. Named
 * EEPROMs are; the name corresponds with a filename.
 *
 * The size of the EEPROM is specified in bytes.
 *
 * A named EEPROM is saved as the smallest file possible. For example,
 * if an EEPROM of 10 motes with 512K of EEPROM is named, it will be
 * 5MB long. If the same named EEPROM is loaded in a later simulation
 * with 20 motes, it will become 10MB long.
 *
 * All functions return 0 on success, -1 on failure.
