/**
 * Create a new container scope using the results of a given query as its contents.
 *
 * @param id
 *          Human-readable name of the scope, typically used to identify where the scope was created. Useful for debugging.
 * @param outer

 *          The context
 * @param query
 *          The query that defines the scope's contents
 * @param originalResource
 *          The original resource
 * @param filters
 *          to apply
 * @param nameFunctions
 *          The name functions to apply
