-/**
- * <h2>Ternary Search Tree</h2>
- *
- * <p>A ternary search tree is a hibrid between a binary tree and
- * a digital search tree (trie). Keys are limited to strings.
- * A data value of type char is stored in each leaf node.
- * It can be used as an index (or pointer) to the data.
- * Branches that only contain one key are compressed to one node
- * by storing a pointer to the trailer substring of the key.
- * This class is intended to serve as base class or helper class
- * to implement Dictionary collections or the like. Ternary trees
- * have some nice properties as the following: the tree can be
- * traversed in sorted order, partial matches (wildcard) can be
- * implemented, retrieval of all keys within a given distance
- * from the target, etc. The storage requirements are higher than
- * a binary tree but a lot less than a trie. Performance is
- * comparable with a hash table, sometimes it outperforms a hash
- * function (most of the time can determine a miss faster than a hash).</p>
- *
- * <p>The main purpose of this java port is to serve as a base for
- * implementing TeX's hyphenation algorithm (see The TeXBook,
- * appendix H). Each language requires from 5000 to 15000 hyphenation
- * patterns which will be keys in this tree. The strings patterns
- * are usually small (from 2 to 5 characters), but each char in the
- * tree is stored in a node. Thus memory usage is the main concern.
- * We will sacrify 'elegance' to keep memory requirenments to the
- * minimum. Using java's char type as pointer (yes, I know pointer
- * it is a forbidden word in java) we can keep the size of the node
- * to be just 8 bytes (3 pointers and the data char). This gives
- * room for about 65000 nodes. In my tests the english patterns
- * took 7694 nodes and the german patterns 10055 nodes,
- * so I think we are safe.</p>
- *
- * <p>All said, this is a map with strings as keys and char as value.
- * Pretty limited!. It can be extended to a general map by
- * using the string representation of an object and using the
- * char value as an index to an array that contains the object
- * values.</p>
