The patch includes the implementation, test cases, and documentation. 

I've included a PDF of the documentation, so you don't have to install the patch and run sphinx to read it.

Back in August I proposed a different implementation that required all in-memory data structure to derive from some yaml classes I had defined.  It was suggested that using a traits based approach could eliminate that intrusiveness and allow YAML I/O to work with any existing data structures by defining template specializations on the existing data types.   Doing that was straight forward with C++11, but getting it to work with older C++ compilers was challenging.  I finally found an alternate way to do the trait testing that should work with all C++ compilers.
