Disconnect from an SSH Server

Demonstrates the Chilkat Ssh.Disconnect method, which closes the current SSH transport. It takes no arguments, is harmless to call when nothing is connected, and may be called repeatedly.

Background: Disconnecting tears down the transport and every channel opened on it; afterward IsConnected is false and NumOpenChannels is 0. Bytes already buffered for a former channel can still be read after disconnect, which is useful when you want to drain a command's final output before releasing the session.
