This PR sets the column TwoStepGraph is told is the id column as the index
on the dataframe loaded into the MgggGraph. As it stands, there's no cheap way to
extract the attributes of a specific vertex if you know it's ID. After this change, the
graph coming out of TwoStepAlgorithm(path, id_column) has a get_vertex_attrs
method that provides cheap access to all or a subset of a vertex's attributes.
