Implement some missing geometry methods, and remove the `Path` type.
...
With the removal of the `Path` type, partitioning multiple paths becomes the responsibility of the user of the library. The reason is that users of the partitioner will frequently want to parallelize over paths via e.g. rayon or Grand Central Dispatch, and we shouldn't mandate a particular parallelism technique.
