21/**
22 * This method searches the Rappture Library Object 'libHandle' for the
23 * node at the location described by the path 'path' and returns its
24 * component name, a concatination of the type, id, and index.
25 * If path is an empty string, the root of the node is used. 'libHandle'
26 * is the handle representing the instance of the RpLibrary object.
27 * Error code, err=0 on success, anything else is failure.
