A VisitorFamily contains a set of recursive operations that are defined over some kind of
tree structure. The `config` parameter specifies how to walk the tree:
- 'getTag' is function which, given a node in the tree, returns the node's 'tag' (type)
- 'shapes' an object that maps from a tag to a value that describes how to recursively
evaluate the operation for nodes of that type. The value can be:
* a string indicating the property name that holds that node's only child
* an Array of property names (or an empty array indicating a leaf type), or
* a function taking two arguments (node, fn), and returning an Array which is the result
of apply `fn` to each of the node's children.
