* \file bbuffer.h
*
* <pre>
* Expandable byte buffer for reading data in from memory and
* writing data out to other memory.
*
* This implements a queue of bytes, so data read in is put
* on the "back" of the queue (i.e., the end of the byte array)
* and data written out is taken from the "front" of the queue
* (i.e., from an index marker "nwritten" that is initially set at
* the beginning of the array.) As usual with expandable
* arrays, we keep the size of the allocated array and the
* number of bytes that have been read into the array.
*
* For implementation details, see bbuffer.c.
* </pre>
