Some templates, especially those invoking modules, may have nested parameters. For example:
{{#invoke:module|user={{{1|{{{user|}}}}}}}}} can be transcluded as {{template|user=value|1=value}}.
In this case, |1= and |user= refer to the same template parameter, and |user= should override |1=
if both are provided.
To specify such hierarchies, use [['1', 'user'], [...]], meaning |1= will be overridden by |user=
whenever a parameter registration detects a lower-hierarchy parameter in the Template instance.
Defines parameter hierarchies for templates, via TemplateStatic.constructor or ParseTemplatesConfig.hierarchies.
