#### Context
Remote hooks are provided with a Context `ctx` object which contains transport specific data (eg. for http: `req` and `res`). The `ctx` object also has a set of consistent apis across transports.

A `Model` representing the user calling the method remotely. **Note:** this is undefined if the remote method is not invoked by a logged in user.
##### ctx.result
During `afterRemote` hooks, `ctx.result` will contain the data about to be sent to a client. Modify this object to transform data before it is sent.
##### Rest
When [asteroid.rest](#asteroidrest) is used the following `ctx` properties are available.
