+ * Class to write to a protobuf stream.
+ *
+ * Each write method takes an ID code from the protoc generated classes
+ * and the value to write.  To make a nested object, call startObject
+ * and then endObject when you are done.
+ *
+ * The ID codes have type information embedded into them, so if you call
+ * the incorrect function you will get an IllegalArgumentException.
+ *
+ * To retrieve the encoded protobuf stream, call getBytes().
+ *
+ * TODO: Add a constructor that takes an OutputStream and write to that
+ * stream as the top-level objects are finished.

+
+/* IMPLEMENTATION NOTES
+ *
+ * Because protobuf has inner values, and they are length prefixed, and
+ * those sizes themselves are stored with a variable length encoding, it
+ * is impossible to know how big an object will be in a single pass.
+ *
+ * The traditional way is to copy the in-memory representation of an object
+ * into the generated proto Message objects, do a traversal of those to
+ * cache the size, and then write the size-prefixed buffers.
+ *
+ * We are trying to avoid too much generated code here, but this class still
+ * needs to have a somewhat sane API.  We can't have the multiple passes be
+ * done by the calling code.  In addition, we want to avoid the memory high
+ * water mark of duplicating all of the values into the traditional in-memory
+ * Message objects. We need to find another way.
+ *
+ * So what we do here is to let the calling code write the data into a
+ * byte[] (actually a collection of them wrapped in the EncodedBuffer) class,
+ * but not do the varint encoding of the sub-message sizes.  Then, we do a
+ * recursive traversal of the buffer itself, calculating the sizes (which are
+ * then knowable, although still not the actual sizes in the buffer because of
+ * possible further nesting).  Then we do a third pass, compacting the
+ * buffer and varint encoding the sizes.
+ *
+ * This gets us a relatively small number number of fixed-size allocations,
+ * which is less likely to cause memory fragmentation or churn the GC, and
+ * the same number of data copies as would have gotten with setting it
+ * field-by-field in generated code, and no code bloat from generated code.
+ * The final data copy is also done with System.arraycopy, which will be
+ * more efficient, in general, than doing the individual fields twice (as in
+ * the traditional way).
+ *
+ * To accomplish the multiple passes, whenever we write a
+ * WIRE_TYPE_LENGTH_DELIMITED field, we write the size occupied in our
+ * buffer as a fixed 32 bit int (called childRawSize), not variable length
+ * one. We reserve another 32 bit slot for the computed size (called
+ * childEncodedSize).  If we know the size up front, as we do for strings
+ * and byte[], then we also put that into childEncodedSize, if we don't, we
+ * write the negative of childRawSize, as a sentiel that we need to
+ * compute it during the second pass and recursively compact it during the
+ * third pass.
+ *
+ * Unsgigned size varints can be up to five bytes long, but we reserve eight
+ * bytes for overhead, so we know that when we compact the buffer, there
+ * will always be space for the encoded varint.
+ *
+ * When we can figure out the size ahead of time, we do, in order
+ * to save overhead with recalculating it, and with the later arraycopy.
+ *
+ * During the period between when the caller has called startObject, but
+ * not yet called endObject, we maintain a linked list of the tokens
+ * returned by startObject, stored in those 8 bytes of size storage space.
+ * We use that linked list of tokens to ensure that the caller has
+ * correctly matched pairs of startObject and endObject calls, and issue
+ * errors if they are not matched.
