+ * A ForwardingProxy creates a Proxy which forwards all method calls to its delegate except for
+ * calls to methods which are implemented by its overrider's class.
+ *
+ * <p>Using this Proxy class makes it possible to use the delegate pattern on any interface without
+ * having to implement any of the interface's methods which directly forward their calls to the
+ * delegate. Using this is intended to make forwarding automated, easy, and less error prone by
+ * making it possible to implement the delegate pattern with an overrider object which only
+ * implements those methods which need overridden functionality and which will not directly forward
+ * their calls to the delegate.
+ *
+ * <p>The overrider object will be assumed to not implement any default java Object methods which
+ * are not overridden, as that would likely not be desirable behavior, and thus the Proxy will not
+ * forward those methods to the overrider unless the overrider overrides them.
+ *
+ * <p>If an overrider needs to make calls to the delegate, this can be achieved by passing the
+ * delegate into the overrider during construction.
