Removed commented line.
Changed graph struct to support new edge data.
Updated parser.

Parsed now parses edges differently. Instead of creating one long list of edges,
each vertex now has its own list of edges. This has two benefits:

1. Easier to use on the GPU.
2. Closer to the raw input data from cheap sensors, which yield adjacency lists
containing IDs of other sensors.
Preparing spring embedding for parse change.
Changed main to allow better parsing.
Simpler graph struct.
Updated parser further

Now correctly parses edges is newest format.
Changed graph files to support new edge format.
Updated spring embedding for new edge format.

Added debug prints.
