[NB] Add scripts for performing routing w/HDF...

Add scripts for performing routing using [HDF] [1] for data storage,
created/modified using [PyTables] [2].  The benefit to using these data
structures is that there are HDF library bindings for many languages, as
well as a tool called [`vitables`] [3] for browsing data.  Moreover, by
storing in a structured form, it is easier to extract data from
experimental results, e.g., for statistical processing.
