Param triggers should be called after use (static path)

[newtang]

Currently, the callbacks in router.param are called before callbacks from router.use. This does not match what the express router does:

The order things should be called:

• use: static
• param functions (in order of appearance in route)
• use: param (not supported yet)
• route middleware / handler

Ideally, the middleware would be added in the appropriate spot for routes that have already been added, and routes that are added after param is called.
