map-wrt and reporting standard implementation

[Eric Dean Tribble <tribble>]

We haven't discussed how to implement reporting standards yet.  I had
an idea last night:  

The reporting standard for a given map operation is installed in the
BertCanopy.  The map operation then attempts to backfollow, filtering
for the reportingStandard of choice.  If it succeeds it return the
eaddress wrt the Stamp to which it backfollowed.  Finally, the
reporting standard is removed from the canopy (asynchronously?).

This can easily implement either AND or OR based reporting standards
based on whether the backfollow returns one solution or all solutions.
