gtsam.readG2o does not read the singlesession_posegraph.g2o file

[pauldeee]

Pretty much as the title states.

When trying to read the singlesession_posegraph.g2o file with gtsam.readG2o() the graph is not compeletely read. This seems be to due to the fact that the singlesession_Posegraph.g2o file does not contain any infomartion matrix data with the edges.

What might be the simpliest and most ideal way to modifiy the saving utility to include an information matrix with the edges data?
