First pass at adminizer and simple test.
Need boost 1.54 for spatial index stuff.
Fixes for latest Mapnik & boost.
Added extra test, fixed adminizer to handle polygons and linestrings.
Actually need Boost 1.56 for geometry.

Avecado does comparisons between lines and areas, so needs this bit in the 1.56 changelog: "the spatial relations which didn't support it (covered_by, touches, within, etc.) now support as input linear and/or areal geometries."
Extend the adminizer to handle points
Merge pull request #17 from MapQuest/adminizer_point

Extend the adminizer to handle points
Added basic coverage reporting.

*Please note*: Since a coverage report build needs all kinds of
special extra files, you will need to `make clean` followed by
re-configuring with the `--enable-coverage` argument. Then
running `make coverage-report` will build you a nice report of
test coverage in the `coverage/` directory.

Note also that you will need `lcov`, `gcov` and `genhtml`
installed. On Ubuntu it's enough to `sudo apt-get install lcov`.
Added docs about testing and test coverage reporting.
Extend the adminizer to handle multipoints along with points

Using the same logic as linestrings
Factored out common geomtry assertions in test.
Factored out more common stuff in adminizer test.
Added simple polygon tests.
Extract common pattern for adminizer tests.
Add a test for multi geometries

mapnik/mapnik#2518 prevents checking the GeoJSON, so instead the feature geometry is queried manually.

mapbox/mapnik-vector-tile#62 prevents MultiPoints from working with mapnik-vector-tile, so they don't work in Avecado either

ref mapbox/vector-tile-spec#18
Extend test coverage to all multi types

Still requires polygon with inner ring coverage

Extend the adminizer to handle multipoints along with points
Merge pull request #21 from MapQuest/adminizer_multipolygon

Adminizer multi*
Merge pull request #18 from MapQuest/coverage

Basic test coverage tool
Fix polygon conversion to boost::geometry.

The conversion wasn't correctly handling the `SEG_CLOSE` command,
and was not setting the counter-clockwise flag correctly on the
polygon type.
