Improve the OWLAPI parser to handle alternative SWRL formulations

[NicolasRouquette]

For example either of the SWRL rules below should be acceptable:

fault-management:PerformanceConstraint(?P) ^ 
fault-management:ViolationExplanation(?V) ^ 
behavior:ElementBehavior(?B) ^ 
analysis:analyzes(?V, ?P) ^ 
analysis:explains(?V, ?B) -> 
fault-management:violates(?B, ?P)

behavior:ElementBehavior(?B) ^ 
analysis:isExplainedBy(?B, ?V)  ^ 
fault-management:ViolationExplanation(?V) ^ 
analysis:analyzes(?V, ?P) ^ 
fault-management:PerformanceConstraint(?P)-> 
fault-management:violates(?B, ?P)

Either one should result in OML in the following rule:

behavior:ElementBehavior ^ 
analysis:isExplainedBy  ^ 
fault-management:ViolationExplanation ^ 
analysis:analyzes ^ 
fault-management:PerformanceConstraint-> 
fault-management:violates
