Add the ability to import data from a file.

[JeffJacobson]

Allow the user to import features from a file.

Formats

Below are formats to consider.

CSV

• [x] This is possible to do client-side using our CSV-Reader. (Implemented)

It is also possible to do this server-side via the ArcGIS REST API's Generate endpoint. The only reason we would need to do it this way would be to support older browsers.

Shapefile

• It may be possible to read shapefiles client-side using mbostock's shapefile library.
• If that doesn't work the ArcGIS REST API's Generate endpoint is another possibility.

  GeoJSON

• Esri's geojson-utils could be used to import GeoJSON.

  TopoJSON

TopoJSON can be converted to GeoJSON.
