area searches

not done.  Just it should work
starting the test.

stupid switch computer commit, really
working with revised geom_utils

getting points inside of a geographic area like county, etc.

prior commit wasn't properly tested, because geom_utils was broken and I
wasn't getting the right thing back

although all that really changed in this was to correct the expected
numbers of detectors I get back inthe tests
test was wrong...memory leakage across requests

While the underlying code is fine, the test was broken and lumping all
requests in a growing array...anyway, fixed that, also changed things
so that I am getting different kinds of detectors in different tests.
