Create "GeoGraph" for Rust

[Bazs]

The GeoNetworkX Python library provides a convenient way to view a set of linestrings, points, and their corresponding arbitrary data as a topologically connected graph.

The TOPO algorithm ensures that all linestrings radiate outward from the center of the graphs, potentially flipping the direction of linestrings if they are facing the wrong way. This requires traversing the graph, which in turn needs the topological graph model to be available. Build this model in software.
