/**
* JSAdapter is java.lang.reflect.Proxy equivalent for JavaScript. JSAdapter
* calls specially named JavaScript methods on an adaptee object when property
* access is attempted on it.
*
* Example:
*
* var y = {
* __get__ : function (name) { ... }
* __has__ : function (name) { ... }
* __put__ : function (name, value) {...}
* __delete__ : function (name) { ... }
* __getIds__ : function () { ... }
* };
*
* var x = new JSAdapter(y);
*
* x.i; // calls y.__get__
* i in x; // calls y.__has__
* x.p = 10; // calls y.__put__
* delete x.p; // calls y.__delete__
* for (i in x) { print(i); } // calls y.__getIds__
*
* If a special JavaScript method is not found in the adaptee, then JSAdapter
* forwards the property access to the adaptee itself.
*
* JavaScript caller of adapter object is isolated from the fact that
* the property access/mutation/deletion are really calls to
* JavaScript methods on adaptee. Use cases include 'smart'
* properties, property access tracing/debugging, encaptulation with
* easy client access - in short JavaScript becomes more "Self" like.
*
* Note that Rhino already supports special properties like __proto__
* (to set, get prototype), __parent__ (to set, get parent scope). We
* follow the same double underscore nameing convention here. Similarly
* the name JSAdapter is derived from JavaAdapter -- which is a facility
* to extend, implement Java classes/interfaces by JavaScript.
