+ provides an interface to register a generic many-to-many mapping between
+ some (namespaced) names and nodes. The goal here is to control the
+ pollution of jamming things into tags or bookmarks (in extension-land) and
+ to simplify internal bits of mercurial: log output, tab completion, etc.
+
+ More precisely, we define a list of names (the namespace) and a mapping of
+ names to nodes. This name mapping returns a list of nodes.
+
+ Furthermore, each name mapping will be passed a name to lookup which might
+ not be in its domain. In this case, each method should return an empty list
+ and not raise an error.
+
+ We'll have a dictionary '_names' where each key is a namespace and
+ its value is a dictionary of functions:
+ 'namemap': function that takes a name and returns a list of nodes
