/**
 * Annotating an field or method with @DataPoint will cause the field value
 * or the value returned by the method to be used as a potential parameter for
 * theories in that class, when run with the
 * {@link org.junit.experimental.theories.Theories Theories} runner.
 * <p>
 * A DataPoint is only considered as a potential value for parameters for
 * which its type is assignable. When multiple {@code DataPoint}s exist 
 * with overlapping types more control can be obtained by naming each DataPoint 
 * using the value of this annotation, e.g. with
 * <code>&#064;DataPoint({"dataset1", "dataset2"})</code>, and then specifying
 * which named set to consider as potential values for each parameter using the
 * {@link org.junit.experimental.theories.FromDataPoints &#064;FromDataPoints}
 * annotation.
 * <p>
 * Parameters with no specified source (i.e. without &#064;FromDataPoints or
 * other {@link org.junit.experimental.theories.ParametersSuppliedBy
 * &#064;ParameterSuppliedBy} annotations) will use all {@code DataPoint}s that are
 * assignable to the parameter type as potential values, including named sets of
 * {@code DataPoint}s.
