Git commit 5b41b26a349967acf2197f9f9228526193fd826e by Christian Mollekopf.
Committed on 27/11/2015 at 16:30.
Pushed by cmollekopf into branch 'develop'.
Introduced a QueryRunner object
The QueryRunner object lives for the duration of the query (so just
for the initial query for non-live queries, and for the lifetime of the
result model for live queries).
It's supposed to handle all the threading internally and decouple the
lifetime of the facade.
