prevent each collision detection code to be triggered by a "touch" (this avoids problems with float inaccuracies)


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@699 bbaffbd6-741e-11dd-a85d-61de82d9cad9

fixed result of "get_free_paths_triangle" for non-collisions (return start and end point instead of nothing)
added representation of Hit objects
simplified forward/backward calculation


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@698 bbaffbd6-741e-11dd-a85d-61de82d9cad9

prevent Exceptions for zero-length lines (e.g. caused by pycam.Geometry.intersection.intersect_circle_line)
