Purpose a Manager/class that builds up the Road Geometry out of parsed information

[francocipollone]

Summary

At the moment https://github.com/maliput/maliput_osm is an example on how maliput_sparse could be used.

maliput_osm contains:

• A RoadGeometryBuilder entity that uses the maliput_sparse's builder api for creating the RoadGeometry out of some structs that contains the obtained information of the underlying format. (maliput_osm::osm::Lane, maliput_osm::osm::Segment).
• A OSMManager entity, that parses the OSM files and fills up a collection of maliput_osm::osm::Segment with that information.

Note:

1. Both maliput_osm::osm::Lane and maliput_osm::osm::Segment are not backend dependant.
2. RoadGeometryBuilder is not backend dependant.

Proposal

We could make them part of maliput_sparse.

1. RoadGeometry builder for creating the RoadGeometry using the builder api and the segment structs.
2. For the Manager/Parser we could define an API that should be implemented by the backend.
   • Manager with a Parser that is injected by the backend.
