/**
 * Install the given resource's description into the given index. Raw JavaScript files will not be indexed. Note
 * that when this method is called for the given resource,it is not yet fully processed and therefore the
 * serialized type model is not added to the index.
 * <p>
 * This is due to the fact that we keep a common resource set for all projects that contains the resources of all
 * projects with unprocessed dependencies,unlike in the IDE case where we have one resource set per open document
 * and load the type models from the index.
 * </p>
 * <p>
 * Since the type models are available in the resource set as long as they may still be referenced,they need not be
 * serialized and stored into the index.
 * </p>
 *
 * @param resource
 *            the resource to be indexed
 * @param index
 *            the index to add the given resource to
