Revised the ontology construction mechanism. Now use a builder to build ontology, in which a data factory is used to create/retrieve objects. The axiom/class expression/property expression visitors (and extensions) in OWLAPI are used to create and load objects.
Also revised the visibility of members in REXObjectSomeValuesFromImpl. Now the property and filler are protected and can be accessed by sub-classes.
The REXMinCardinalityRestrictionImpl construction is revised. Now the filler will be an cardinality atomic instead of the original atomic. It will also be preserved in the corresponding property.some map.
Also using OWLPAI v4.0.1 now.
