"""Board data model for freeroute.

The data model a parsed DSN produces and the (future) router operates on:
layers, units, coordinate transform, nets, clearance matrix, the item hierarchy,
and the :class:`BasicBoard` container. :func:`build_board` constructs a board
from a :class:`~freeroute.dsn.model.DsnBoard`.

The routing operations (``RoutingBoard``) and the spatial ``ShapeSearchTree``
belong to the router phase.
