[tracker/dbus-fd-experiment: 3/19] Add Steroids example client



commit 2dec7abb595f2cb9270328114f4ccf0ede21b6d5
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.
