## eq: are two agents observationally equivalent (weakly bisimilar)?

`eq(A,B);`

### Notes

Returns true iff the agents are related by some weak bisimulation.
R is a weak bisimulation iff PRQ implies
whenever P -a-> P' there exists Q' st Q =^a=> Q' and P' R Q' and

whenever Q -a-> Q' there exists P' st P =^a=> P' and P' R Q'.
