 * NOT YET IMPLEMENTED
 * UNIT TEST FAILS *
 *
 * IO wrapper for sockets
 *
 * This is a simple IO wrapper.  The idea is, to have one single
 * interface to open/read/write/close for any operation needed, such
 * that the access can be abstract to the calling function.
 *
 * Also there is a generic easy error handler, which processes all
 * errors.
