Skeleton code for time-range test (section 9.9)

Skeleton code for time-range test (section 9.9)

After finally getting to the point where we are recursing up
through both the nested components and the nested queries in a
way that matches them properly, we are now able to start writing
the individual property and parameter queries defined in the RFC.

time-range (section 9.9) is the obvious first choice to implement
because it is the most useful.  Wrote and bound the skeleton
function to do this.
