add_server_layer

Add a server layer to a tower. This layer
will run before the 'shiny' app's server function. This
is useful for adding custom logic to the server function
without modifying the original server function.

The best way to implement middle ware for 'shiny' Applications. 'tower'
is designed to make implementing behavior on top of 'shiny' easy with a layering
model for incoming HTTP requests and server sessions. 'tower' is a very minimal
package with little overhead, it is mainly meant for other package developers
to implement new behavior.
