REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls. Xojo Plugin

//   OK, the SSH tunnel is setup.  Now open a channel within the tunnel.
//   (Any number of channels may be created from the same SSH tunnel.
//   Multiple channels may coexist at the same time.)

//  This example connects to a REST server through the SSH tunnel.
//  It will connect to the Amazon AWS service for this example.
