Experimental Tagged types C++ library C++14/17.

This code will eventualy form the basis of several formal proposals to add a overload function, a match function and a tags library to the C++ standard library.

This code is undocumented, untested, constantly changing, and generally not fit for any use whatsoever.

Most of the source code in this project are mine, and those are under the Boost Software License.

I have adapted the make_overload class and the match functions from https://github.com/JasonL9000/cppcon14.

The code is known to work on the following compilers:

• GCC 4.9.0 -std=c++1y
