Generate the splines with the desired resolution, instead of the default one.

See merge request !3

Added functions to generate the geometry from a given starting point.

Added support to handle lane connectivity and imporved the lane geometry generation.

Merge branch 'master' of ssh://gitlab.iri.upc.edu:2202/mobile_robotics/autonomous_driving/autonomous_driving_tools

Added a feature to specify a set of path types to import, each with a set of highways and other tags.
Each path type has its own parameters to generate the geometry.

Solved a bug when creating a new geometry object: the sale factor is...

See merge request !2

Stop the spline generation if the number of points gets too big (generation diverges for some reason)

When loading a map (opendrive or OSM) free any previous data.

Solved a bug when getting a part of the original spline: The value to specify to the end is max double and not -1.

Added functions to set/get the UTM zone to use (default 31).
Used the file header bounds to compute the center of the map (instad of the node locations).

Added a function to check whether a given input lane is connected to any output lane.
