rdflib extension adding SQLAlchemy as an AbstractSQLStore back-end store

SQLAlchemy store formula-aware implementation. It stores its triples in the following partitions:

• Asserted non rdf:type statements

• Asserted rdf:type statements (in a table which models Class membership). The motivation for this partition is primarily improved query speed and scalability as most graphs will always have more rdf:type statements than others.

• All Quoted statements

In addition it persists namespace mappings in a separate table
