/**
 * Marks an implicit cast method. Implicit cast methods are expected to have a return type, the
 * target type and a source type the first parameter type. Any other method signature is not
 * allowed. The source and target type must not be the same type. The order of implicit casts
 * determines the order in which they are checked. This is important to optimize performance but
 * also to provide a precedence for ambiguous type checks.
 * 
 * Example usage:
 *
 * 
 * @TypeSystem
 * public static class ExampleTypeSystem {
 *
 *     @ImplicitCast
 *     public static double castInt(int value) {
 *         return value;
 *     }
 *
 *     @ImplicitCast
 *     public static double castShort(short value) {
 *         return value;
 *     }
 * }
 *
 * 
 *
 * For details on how to use implicit casts see {@link TypeSystem}.
 *
 * @see TypeSystem
 * @since 0.8 or earlier
