[Moose-dev] [Better Comment Initiative] FamixAssociation

FAMIXAssociation is an abstract superclass for relationships between Famix named entities. It defines a polymorphic API refined by subclasses: essentially from, to, next and previous. implementations can have multiple ends and properties. For example, FAMIXInheritance has: (i) From mapped to the subclass; (ii) To mapped to the superclass. Next and Previous properties provide an order of the appearence of these associations in code. The order is calculated within a particular relationship for example, method invocation order within a calling method (from). For example in java, the following code method a() { b(); c(); } will produce two invocation associations first from method a to method b, and second from method a to method c. These associations are bound together and can be navigated with previous and next.
