Adds xpath matching to object trees

This module adds XPath-style matching to your object trees. This means that you can find nodes using an XPath-esque query with 'match()' from anywhere in the tree. Also, the 'xpath()' method returns a unique path to a given node which can be used as an identifier. To use this module you must already have an OO implementation of a tree. The tree must be a true tree - all nodes have a single parent and the tree must have a single root node. Also, the order of children within a node must be stable. *NOTE:* This module is not yet a complete XPath implementation. Over time I expect the subset of XPath supported to grow. See the SYNTAX documentation for details on the current level of support.
