Improved fc::value to use enum types instead of strings.
Moved code from header to cpp file
Added extra utility method to simplify syntax for generating key-value pairs for errors/logs.
Removed need to create copies when casting strings, arrays, or objects from values
- removed polymorphic reflection, made static_reflect default because
there are cases such as deserializing an array that you need more
information than the runtime reflection can provide such as the
ability to resize arrays and know the array content type.
- refactored iostream, sstream, fstream to be much simpler, fewer
indirections, and fixed getline.
- json parsing works using code from mace.
- value is reimplemented based upon mace::rpc::value and no longer uses
the runtime reflection that was removed.
- moved the typename utility to its own header
