because i dont want them to show up in tab completion

(otherwise e.g. you'd get both geosnap.community and geosnap.Community when you tab)

i want to trigger a travis build, so i'll do the docs in a separate PR

[knaaptime]

tests pass locally but i cant get the build to trigger on travis...

The travis CI seems to have not been triggered for the past three months. The last CI build on the master branch was from PR https://github.com/spatialucr/geosnap/pull/131

good catch. Looks like @suhanmappingideas got one to trigger from the vizsu branch and that seems to have gotten things moving. how strange

I reworked the tests and CI config so that as long as you have the LTDB and NCDB environment variables set, tests should pass on forks

(everything is passing on mine) this should be ready to go
