+/**
+ * This class implements the tag tree encoder. A tag tree codes a 2D
+ * matrix of integer elements in an efficient way. The encoding
+ * procedure 'encode()' codes information about a value of the matrix,
+ * given a threshold. The procedure encodes the sufficient information
+ * to identify whether or not the value is greater than or equal to
+ * the threshold.
+ *
+ * <P>The tag tree saves encoded information to a BitOutputBuffer.
+ *
+ * <P>A particular and useful property of tag trees is that it is
+ * possible to change a value of the matrix, provided both new and old
+ * values of the element are both greater than or equal to the largest
+ * threshold which has yet been supplied to the coding procedure
+ * 'encode()'. This property can be exploited through the 'setValue()'
+ * method.
+ *
+ * <P>This class allows saving the state of the tree at any point and
+ * restoring it at a later time, by calling save() and restore().
+ *
+ * <P>A tag tree can also be reused, or restarted, if one of the
+ * reset() methods is called.
+ *
+ * <P>The TagTreeDecoder class implements the tag tree decoder.
+ *
+ * <P>Tag trees that have one dimension, or both, as 0 are allowed for
+ * convenience. Of course no values can be set or coded in such cases.

+ * bitrate, the overall target bitrate will still appear as the last
+ * optimization point, even though it does not follow the increasing target
+ * bitrate order of the other optimization points. The rate allocator is
+ * responsible for eliminating layers that have target bitrates larger than
+ * the overall target bitrate.
