Description

TypeResolvers should annotate their source nodes with their result types, in much the same way as the name resolvers annotate their source nodes with a Path.

Bonus points if this can be done automatically (i.e. without having to manually call node.annotate(type, Annotations.Type))!

Contributor guide

Research direction
Examine the existing name resolver to understand how it annotates nodes with Path, then apply a similar approach for TypeResolvers to annotate nodes with types. Consider using a delegate or automatic annotation mechanism.
