/**
* Helper for defining a managed interface.
*
* Managed interfaces virtually derive from coherence::lang::Object, and
* include a set of well known features, which are auto-generated by this
* helper class:
*
* - Handle/View/Holder definitions
* - virtual interface inheritance of up to 16 interfaces
*
* The template takes two parameters:
*
* - The name of the interface being defined
* - An optional list of interfaces to extend, indicated as
*   implements<i1, i2, ...>
*
* A normal interface definition would be:
* @code
* class MyInterface
*   : public interface_spec<MyInterface,
*       implements<SomeInterface, SomeOtherInterface> >
*   {
*   public:
*       // pure virtual method definitions....
*   };
* @endcode
*
* @see implements
