CitySDK LD API v0.9 - Matching API

This gist contains the code of the matching API of the old version of CitySDK LD API.

api.rb was part of the Sinatra REST API, this code was triggered by a POST request, and called the code in the other files.

Ruby script to convert stops.txt and shapes.txt to GeoJSON.

I've been experiencing stack level errors in Hashie's mash.rb, when POSTing somewhat large GeoJSON files to a Grape endpoint. I'm using Grape 0.7.0.

To replicate the bug, do the following:

Open two terminals, run rackup in one,
and ./bug.sh in the other.

The Grape/Rack terminal will output:

[2014-06-17 11:18:37] ERROR SystemStackError: stack level too deep

A treemap recursively subdivides area into rectangles; the area of any node in the tree corresponds to its value. This example uses color to encode different packages of the Flare visualization toolkit. Treemap design invented by Ben Shneiderman. Squarified algorithm by Bruls, Huizing and van Wijk.
