Detailed Description

template<class T>
class v8toolkit::JSWrapper< T >

C++ types to be extended in javascript must inherit from this class. Example: class MyClass{}; class JSMyClass : public MyClass, public JSWrapper {}; Now, JSMyClass can be used as a MyClass, but will intercept calls to its methods and attempt to use the javascript object to fulfill them, falling back to the C++ class methods of MyClass when necessary Any class inheriting from this (e.g. JSMyClass) must have the first two parameters of its constructor be a v8::Local<v8::Context>, v8::Local<v8::Object>

It's easy to end up in infinite recursion where the JSWrapper object looks for a javascript implementation to call instead of calling the native C++ implementation, but finds its own JS_ACCESS function that its already in an proceeds to call itself. This flag stops that from happening - at least in naive situations. Marked as mutable because it needs to be changed even from within const methods
