    """
    Get data from the mine based on the target, function and tgt_type

    This will actually run the function on all targeted minions (like
    publish.publish), as salt-ssh clients can't update the mine themselves.

    We will look for mine_functions in the roster, pillar, and master config,
    in that order, looking for a match for the defined function

    Targets can be matched based on any standard matching system that can be
    matched on the defined roster (in salt-ssh) via these keywords::

    CLI Example:

    .. code-block:: bash

        salt-ssh '*' mine.get '*' network.interfaces
        salt-ssh '*' mine.get 'myminion' network.interfaces roster=flat
        salt-ssh '*' mine.get '192.168.5.0' network.ipaddrs roster=scan
