 * <p><b>Purpose</b>: This interface specifies methods to create parse trees
 * and parse tree nodes.
 * <p><b>Responsibilities</b>:
 * <ul>
 * <li> Used by the EJBQLParser to create an internal representation of an
 * EJBQL query.</li>
 * <li> Abstract from concrete parse tree and parse tree node implementation
 * classes.</li>
 * <li> The parse is created in a bottom-up fashion. All methods takes any
 * child nodes for the parse tree node to be created as arguments. It is the
 * responsibility of the new&lt;XXX&gt; method to set the parent-child relationship
 * between the returned node any any of the child nodes passed as arguments.</li>
