Known Subclasses:

Base class for file format specific random access (PRIVATE).

This is subclasses in both Bio.SeqIO for indexing as SeqRecord
objects, and in Bio.SearchIO for indexing QueryResult objects.

Subclasses for each file format should define '__iter__', 'get'
and optionally 'get_raw' methods.
