class Server

Requests that the `Controller` at the other end of the

`server_end:Controller` channel be associated with the `View`

referenced by `view_ref`.

When `Controller.RequestShow()` is called, the `Controller`

implementer will will attempt to provide a keyboard optimized

for the entry of `text_type` (unless the type is overridden by a

call to `Controller.SetType()`).

Implementers of `ControllerCreator` _should_ use knowledge of

the associated `View`'s focus state to apply access controls to

calls made on `Controller`. See documentation of the `Controller`

methods for further details.

Consumers of `ControllerCreator` may freely drop their Creator

connection, without affecting their Controller(s).

|bind_handler| returns a handler that binds incoming connections to this

server implementation.

The returned handler borrows the server instance.

The server must outlive the provided |dispatcher|. Only after

the dispatcher is shutdown will it be safe to destroy the servers.

The server should not be moved.
