[tracker/dbus-fd-experiment: 3/49] Add Steroids example client

[Martyn James Russell <mr src gnome org>]

commit eaed6187fd1a3957c6cb88755788d6cc87a770a9
Author: Adrien Bustany <abustany gnome org>
Date:   Mon May 24 11:54:48 2010 -0400

    Add Steroids example client
    
    This commit adds a steroids-sparql program. This program shows how to
    use the tracker_resources_sparql_query_iterate function to do a query
    and fetch the results. It does exactly the same thing as
    tracker-sparql -q.
