Restructure repo so it's clear which approach is using the streaming, and which is using Bloom filters

[dkoslicki]

The Bloom filter approach (presented in this paper) corresponds to:

1. MakeDNADatabase.py
2. QueryDNADatabase.py
3. MakeNodeGraph.py

The new (as of yet unpublished) implementation that uses ternary search trees and streaming consists of

1. MakeStreamingDNADatabase.py
2. MakeStreamingPrefilter.py
3. StreamingQueryDNADatabase.py
4. StreamingQueryDNADatabase_queue.py (depreciated)

Need to clarify this in the repo structure, as well as Update the documentation
