Detailed Description

The execution process may be optimized by not using visitors. Having instructions implement a method that returns a flow action directly.

A FlowAction is what has to be done with the route. DEFAULT is the default action which is normally "go to the next term", or if the last term, ACCEPT.

The semantic check should get rid of these.

Execute the policies.

Execute a policy.

Parameters:
