v4.0.0

This is a major redesign milestone focusing on a set of core pillars (and learned lessons):

• OWL2/XML: W3C datamodel for representing OWL2 ontologies, at the core of the library expressivity
• Protégé: standard de-facto IDE for ontologists, used as functional test platform of the project
• Async API to help development of efficient and modern .NET solutions
