// The command adapters are used to handle commands that do not accept a body

// Example:
//
// fn := func(ctx context.Context) (interface{}, error) {
// // do something
// return nil, nil
// }
//
// r.Get("/foo", adapters.Command(fn, http.NoContent))

// CommandID is the same as the Command adapter but it accepts a UUID as a parameter
// in the URL. The parameter name is passed as the first argument.

// // do something
// return nil, nil

//
// r.Get("/foo/{id}", adapters.CommandID("id", fn, http.NoContent))
