find-inferencing-state

Finds a known inferencing state.

find-inferencing-state name &key if-does-not-exist => state

`name`⇩	Any object.
`if-does-not-exist`⇩	Either `:error` or `:create`.

state

An inferencing state.

The function find-inferencing-state finds and returns an inferencing state named by name.

If an inferencing state with the same name already exists (as compared using eql), it is returned.

Otherwise, the value of if-does-not-exist determines what happens:

`:error`	A continuable error is signaled. Invoking the continue restart creates and returns a new inferencing state.
`:create`	A new inferencing state is created and returned.
