assign_protein_type tested against a single hard-coded sequence input.
The next step is to iterate over all records in the HDF5 collection
that don't have a type assigned and to assign a type value.
Consideration of the anlaytical tools to be used and their load
features should be considered to determine if the HDF5 container adds
any value. In general custom C programs should get value out of
saving the results of reading and ASCII to binary conversion steps
back out to HDF5.
