 - `Context.RecordBody()` same as the Application's `DisableBodyConsumptionOnUnmarshal` configuration field but registers per chain of handlers. It makes the request body readable more than once.
 - `Context.IsRecordingBody() bool` reports whether the request body can be readen multiple times.
 - `Context.ReadHeaders(ptr interface{}) error` binds request headers to "ptr". [Example](https://github.com/kataras/iris/blob/master/_examples/request-body/read-headers/main.go).
