Represents the state of the panes inside the structure-tool router
The structure tool stores the state of the current panes inside of the router.
The panes are stored in groups delimited in the URL by ;.
In each group, there can be one or more sibling (aka split) panes delimited
by |.
Each item pane can contain it's own parameters and payloads
Per item pane in each group, if not specified separately, the ID, params,
and payload will be inherited from the first item pane in the pane group
(unless it's an exclusiveParam)
E.g. /structure/books;book-123|,view=preview will parse to:
[ // first pane group [{id:'book'}],
// second pane group [ [ // first pane item {id:'book-123'}, // second pane item {id:'book-123', params: {view:'preview'}}, ], ], ]
