Filtering relations to compare using meta-description

[AntoninGoslin]

We need to find a way to filter useless comparisons on relations in our models( things like replicas maybe?)

Between the two versions , we have 50k more relations, seems to much.

[AntoninGoslin]

I added a filter that will skip all of the useless relations involving the opposite side of a relation.
For exemple: If we have a class with one method in it, we have two relations:

• from class to method: we have the method relation
• from method to class : we have the parentType
  In this case, this is useless to compare the relation parentType, because , if the classes have the same mehods, so the methods have the same parentType, we don't need this relation.
