Holmes 0.1.0

This is the first release of Holmes potentially suitable for use by others. This is certainly still not a finished product, but it is documented and in a moderately well tested state.

Features:

• Persistent Datalog (Datalog, no negation, persists in PostgreSQL)
• Where Clauses (Call native code when a rule matches to generate the contents of the head clause)
• HTML Rendering (Simple table rendering of a selected predicate)
• EDSL for Datalog (Collection of macros which allows the user to avoid writing long form rule/fact declarations)
