replicate the Graph embeddings experiment

[nicolasfredesfranco]

I've been trying to replicate the Graph embeddings experiment present in section 5.3 of the paper. The other two experiments of section 5 are explicit in the readme with their input parameters. Could anybody help me to do that? I downloaded the data sets used in the graph embedding experiment from their sources, but those are in a format different to CSV, and I am not sure if I just need convert their to CSV and use the code with "-model" parameter equal to "csv" or make other things.
