/**
 * Given a JSON tree, find the element specified by the path (or the root if path is null). In that subtree,
 * recursively traverse all elements, and expand all String typed right hand side values.  If a macro cannot be
 * expanded due to the cluster object missing certain data, that macro will be left unexpanded.
 *
 * @param json A JSON tree/*  w  w w.  j  a  v  a2 s  .c om*/
 * @param path the path to expand under
 * @param cluster the cluster to use for expanding macros.
 * @param nodes the cluster nodes to use for expanding macros.
 * @param node the cluster node to use for expanding macros.
 * @return a new JSON tree if any expansion took place, and the original JSON tree otherwise.
 * @throws SyntaxException if a macro expression is ill-formed.
 * @throws IncompleteClusterException if the cluster does not have the meta data to expand all macros.
