Add 3.0.2 release date
Fix equality testcase
Fix example clean target in makefile for operating systems that don't use .so as shared library extension
Fix function naming conflict with class overloads.

This fix takes into account the classname while generating overload
handlers.

Example:

If you have two classes:

  class A {
    public:
      void doSomething(int);
      void doSomething(double);
  };

  class B {
    public:
      void doSomething(int);
      void doSomething(double);
  };

Before this patch, the overload handlers for A::doSomething and
B::doSomething create conflicting names and function redefinition errors
are caused.

After the patch, the overload handlers are named classname_doSomething
and no longer conflict.

This is might not the best way to implement this, but it
solves a critical problem on large projects, and specifically can affect
operator overloads that are being wrapped.
