Added TypeInformation interface and infrastructure to discover generic types given a basic type that binds generic types. Starting from that you can then traverse TypeInformations for fields by calling getProperty(…). A subsequent call to getType() will then return the resolved type.
Adapted the Basic mapping infrastructure to accomodate the TypeInformation interfaces where necessary. In most cases it was just about using TypeInformation instead of class as we have to keep track of the parent types that (in case of a generic field) determine the actual type of sub fields. BasicMappingContext is now using the TypeInformation instance created for PersistentEntity as key for the cache. This is necessary as generic types (e.g. Foo<T>) might be used inside different entities that type T to something different.
Created isMap() and isArray() on PersistentProperty to align to isCollection().
