/** Retrieve the root expression of the internal
 *  compiled form of this XPath expression.
 *
 *  <p>
 *  Internally, Jaxen maintains a form of Abstract Syntax
 *  Tree (AST) to represent the structure of the XPath expression.
 *  This is normally not required during normal consumer-grade
 *  usage of Jaxen.  This method is provided for hard-core users
 *  who wish to manipulate or inspect a tree-based version of
 *  the expression.
 *  </p>
 *
 *  @return the root of the AST of this expression
