6106	New map[] directive to augment qi::symbols when doing binary parsing	oakad@…	Joel de Guzman	"qi::symbols is an exceptionally useful parser, but it is strongly tied to character strings as its input type. When doing binary parsing, one of the common tasks is de-serializing objects from the binary stream, an activity which can strongly benefit from Nabialek trick (http://boost-spirit.com/home/articles/qi-example/nabialek-trick/). Another common use case are extensible enum types, a feat which is somewhat cumbersome to handle with attribute transformations.

This is my first attempt at implementing a qi directive, so it's probably far from perfect. One of the immediate shortcomings I want to resolve is direct dependency on std::map which is also passed by value between instances.

The implementation and a short example demonstrating Nabialek trick is attached."	Patches	new	To Be Determined	spirit	Boost Release Branch	Not Applicable
