Documentation

Create multiple associations

user> (is= :car :vehicle)
({:vehicle :car, :car :vehicle})
user> (is= :two-door :car)
({:car :two-door, :two-door :car} {:vehicle :car, :car :vehicle})
user> (and 
       (e= :car :vehicle)
       (e= :car :two-door))
true

Order doesn't matter

user> (is= :book :many-pages)
({:many-pages :book, :book :many-pages})	
user> (e= :book :many-pages)
true
user> (e= :many-pages :book)
true

Remove facts from scope

user> (isnot= :book :many-pages)
()
user> (e= :many-pages :book)
false
user> (e= :book :many-pages)
false

Temprorary scoping

user> (let-equal 
       [:apple :fruit
	:fruit :sweet
	123 321]
       (and
        (e= :fruit :apple)
        (e= :sweet :fruit)
        (e= 321 123)))
		   
true
