org.apache.lucene.facet.enhancements.association.AssociationProperty
A {@link CategoryProperty} associating a single integer value to a{@link CategoryAttribute}. It should be used to describe the association between the category and the document.
This class leave to extending classes the definition of {@link #merge(CategoryProperty)} policy for the integer associations.
Note: The association value is added both to a special category list, and to the category tokens. @see AssociationEnhancement @lucene.experimental
