This sets up a name resolution framework trying to follow rust-dev guide

We can use the NodeId from the AST to generate apropriate mappings for all
names and types. Ribs are the scopes for names being instansiated, and
reference to defintion tables allows all names to be resolved to NodeId's.

Later on NodeIds will map over to HIR ids allowing for type resolution.
