<P>
This class is used to create a tree structure of objects. Each element in the
tree is also a key to the next node down in the tree. It provides many ways
to add objects and branches, as well as many ways to retrieve.
<p>
HashTree implements the Map interface for convenience reasons. The main
difference between a Map and a HashTree is that the HashTree organizes the
data into a recursive tree structure, and provides the means to manipulate
that structure.
<p>
Of special interest is the <A HREF="../../../../org/apache/jorphan/collections/HashTree.html#traverse(org.apache.jorphan.collections.HashTreeTraverser)"><CODE>traverse(HashTreeTraverser)</CODE></A> method, which
provides an expedient way to traverse any HashTree by implementing the
<A HREF="../../../../org/apache/jorphan/collections/HashTreeTraverser.html" title="interface in org.apache.jorphan.collections"><CODE>HashTreeTraverser</CODE></A> interface in order to perform some operation on the
tree, or to extract information from the tree.
