## HopObject#size_macro

Render the number of child nodes of the HopObject. Three cases are distinguished which can be customized by setting param.verbose to "true" and defining the corresponding field of the `param` argument:

1. param.none - not a single child node
2. param.one - exactly one child node
3. param.many - more than one child node
