[boost] [GTL] redesign checked into sandbox

I checked a gtl project into the sandbox so that I can keep postings to
the list more brief while allowing people to see the up to date and
correctly compiling state of the re-design and re-implementation of the
library interfaces.

The main header file is gtl.h, which includes the others and defines
free functions that may rely on any of the geometry concepts when
instantiating the template function.

A recent change is  to the design is that rather than using SFINAE to
overload a free function on return type I now call a meta-function that
looks up from the related concept and provides the correct return type
based upon the args given (see get() in gtl.h).  This eliminates the
need to register the return type in a specialized traits class since the
concept can provide it for the given type generically.

The code in the sandbox is intended to conform to boost standards.  Feel
free to point out instances where I may have failed to do so.
