Decorator: TransportDecorator(ChildTransport)
=============================================

Returns a `TelemetryTransport` constructor that can be used in place of any
other transport adapter. It works by registering hooks in the underlying
transport adapter for measuring node performance and storing those metrics on
disk, which can be used for [more intelligent routing](router-decorator.md).

## Usage Example

```js
var kad = require('kad');
var telemetry = require('kad-telemetry');

var TelemetryRouter = telemetry.RouterDecorator(kad.Router);

var transport = new TelemetryTransport(contact, {
  telemetry: {
    filename: 'path/to/telemetry.data',
    metrics: [
      // defaults to all metrics, but you can specify explicity
    ]
  }
});

var node = new kad.Node({
  transport: transport,
  storage: kad.storage.FS('path/to/storage')
});
```
