CPP1114 — Add Delegation-Based Interface Implementation

The current IDL to C++11 language mapping only describes an inheritance based interface implementation in chapter 6.26.6. The IDL to C++ language mapping also described a delegation based implementation. We propose to add a delegation based implementation to the IDL to C++11 specification.

I will attach a proposal new chapter 6.26.7, only the formatting of IDL and C++ types has to be done in the final document, especially types in the text itself need to be formatted. In the first paragraph there is a number 126, that has to be updated.
