/**
 * Annotating a {@link org.junit.experimental.theories.Theory Theory} method
 * parameter with @ParametersSuppliedBy causes it to be supplied with
 * values from the named
 * {@link org.junit.experimental.theories.ParameterSupplier ParameterSupplier}
 * when run as a theory by the {@link org.junit.experimental.theories.Theories
 * Theories} runner.
 * 
 * In addition, annotations themselves can be annotated with
 * @ParametersSuppliedBy, and then used similarly. ParameterSuppliedBy
 * annotations on parameters are detected by searching up this hierarchy such
 * that these act as syntactic sugar, making:
 * 
 * <pre>
 * &#064;ParametersSuppliedBy(Supplier.class)
 * public &#064;interface SpecialParameter { }
 * 
 * &#064;Theory
 * public void theoryMethod(&#064;SpecialParameter String param) {
 *   ...
 * }
 * </pre>
 * 
 * equivalent to:
 * 
 * <pre>
 * &#064;Theory
 * public void theoryMethod(&#064;ParametersSuppliedBy(Supplier.class) String param) {
 *   ...
 * }
 * </pre>
