 *         1) angular.$http cannot be declared as a callable type.
 *            Its helper methods should be used instead.
 *         2) angular.$http.delete cannot be added as an extern
 *            as it is a reserved keyword.
 *            Its use is potentially not supported in IE.
 *            It may be aliased as 'remove' in a future version.
