This adds methods to the network and various components for "visiting" Metrics and Paths. These methods are useful for finding, for example, all paths in a model.
The traits are trivially implemented for common types. New derive macros replace the previous PywrNode macro. These macros generate implementations of the two traits for the struct and enum types currently used in the schema.
Outstanding items:
[ ] Should there be separate visit_ and walk_ methods. Where walk would be recursive, but visit not?
