Collision detection between mesh (tree) and line

[Anders Logg (Chalmers)]

Extend BoundingBoxTree to compute intersection between mesh and a line defined by two points:

compute_collisions(Point& p0, Point& p1);
compute_entity_collisions(Point& p0, Point& p1);

Should be relatively easy to implement. Create bb spanned by the two points, then compute collisions with bb, then check collision with entity.

This turned out not to be needed, for now, so will postpone this issue.
