/**
 * Pluggable directive that handles the #parse()
 * statement in VTL.
 *
 *  * Notes:
 * -----
 *  1) The parsed source material can only come from somewhere in
 *    the TemplateRoot tree for security reasons. There is no way
 *    around this.  If you want to include content from elsewhere on
 *    your disk, use a link from somwhere under Template Root to that
 *    content.
 *
 *  2) There is a limited parse depth.  It is set as a property
 *    "directive.parse.max.depth = 10" by default.  This 10 deep
 *    limit is a safety feature to prevent infinite loops.
