Serializing PyGnome objects in the redis session is too heavy and problematic for Cython objects.
Changed the redis session management of our Model objects into a simpler run-time memory management scheme.
The Model step API now properly handles the stop iteration exception as well
as any unexpected exceptions.
fixed spillable area in Norfolk bna to use commas (bna format) rather than whitespace as delimiters
Merge branch 'master' of https://trac.orr.noaa.gov/git/WebGnomeAPI
Added unit tests for SpatialRelease API
Created a Web API method for getting the GeoJson from a Map object.
Created some helper methods for more easily accessing the osgeo package.
lower case geojson
Setting up a —skipslow option for py.test (We want to run all tests by default).
Adding a unit test area for testing full-run scenarios.
Added filtering to bna features.

Currently just removing the Spillable area polygon for now.
filter out map bounds
Lowercase ‘geojson’ in the map unit-tests.  If we reference an unimplemented map type, we need to raise a not-implemented exception
