Add Path.Index helper method (#56)

An analysis of user code shows that Path.Last was not sufficient and
that what users really wanted was an easy want to do negative indexing
without needing to constantly check for out-of-bounds.

Thus, add a generic Index method that does not panic on out-of-bounds
accesses and supports negative indexing.
