Issue #15 made NodeMapper and PropertyMapperBase public - I want to be able to use these to query NodeMappers with LINQ.
Made NodeMappingContext and NodeMapper public to support querying the mapping table by doctype (i.e. generic view construction with LINQ, gist will follow to demonstrate)
Merge pull request #16 from codegecko/master
