gather real data

[thfield]

right now our route data is (mostly) made up. we need to gather information about routes:

• descriptions
• lane types (separated, sharrows, etc)
• distance
• elevation

we should have standardized json or csv format, that can be input to the db from what we develop in #31

[thfield]

distance and elevation may be able to be inferred from route geojson data, distance can be calculated from turf.js with route file

need to contact mapbox about surface api for elevation display

[thfield]

elevation profiles now pre-calculated by lib/assets/elevations.js node script and saved to model as Bikeroute.elevation

distance data is also calculated by lib/assets/genSeeds.js script and saved as Bikeroute.distance

[thfield]

"about" data for neighborhoods need to be gathered as well
