Update build script to work locally

:cactus: This build fails because of the issue addressed in #12 
* Update readme to link to travis build
* Update readme to acknowledge multiple geojson files
* Update ci build script to work locally
* Remove local ci build script
* Update ci build script text to make pass/fail more obvious  

The directory is `geojson`, not `routes`.  We have some point features in there, which aren't technically routes, so I renamed it.
