Attributes

The idea is simple: Nodes can be filled in with as many attributes as required when exploring, and these attributes can then be passed to a Model, but when using or exporting a Model, only the basic attributes (i.e., path, foundType, descriptiveType, unique, default, description, choices, regex) are used.

When using or exporting a Tree, however, everything is retained.

Prog stuff

• Exporting a traversal from a Node requires to have a traversal; such traversal is generated with argonodes.appliers.make_traversal, which explicitly discards fieldName, data, parent, children, and traversal.
• The traversal is regenerated when using argonodes.nodes.Node.export_traversal, which is used by argonodes.models.Model.add_traversal.
• ... TODO, cf. #54.
