Variable Documentation

vector<MFAS::KeyPair> edges

Initial value:

= {make_pair(3, 2), make_pair(0, 1), make_pair(3, 1),
                         make_pair(1, 2), make_pair(0, 2), make_pair(3, 0)}

We (partially) use the example from the paper on 1dsfm (https://research.cs.cornell.edu/1dsfm/docs/1DSfM_ECCV14.pdf, Fig 1, Page 5) for the unit tests here. The only change is that we leave out node 4 and use only nodes 0-3. This makes the test easier to understand and also avoids an ambiguity in the ground truth ordering that arises due to insufficient edges in the geaph when using the 4th node.
