I have a nested array that represents a sites hierarchy / pages.  
Naively, I though I could walk this array… and call `$app->group()` to “open” a group and then `$app->any()` to add groups or routes to the current group… then perhaps some sort of `groupEnd()` or `popGroup()` to close the group while walking the array… However it appears that `$app->group()` requires a closure param from which route are added to the group…

Question 1: Is it possible to dynamically / pragmatically create groups?.

Question 2: Slim has the `routerCacheFile` option… is it possible to “skip right to the cachefile” and not even call `$app->get()`, `$app->any()`, etc?

Question 3: Best practice for pragmatically generating a site-map ?

Seems like I’ll need to define routes and define a site-hierarchy separately…
