    Primary/default implementation of SSH agent forwarding functionality.

    Simply instantiate this class, handing it a live command-executing session
    object, and it will handle forwarding any local SSH agent processes it
    finds.

    For example::

        # Connect
        client = SSHClient()
        client.connect(host, port, username)
        # Obtain session
        session = client.get_transport().open_session()

    Client interface for using private keys from an SSH agent running on the
    local machine.  If an SSH agent is running, this class can be used to
    connect to it and retreive `.PKey` objects which can be used when
    attempting to authenticate to remote SSH servers.

    Upon initialization, a session with the local machine's SSH agent is
    opened, if one is running. If no agent is running, initialization will
    succeed, but `get_keys` will return an empty tuple.
