f6dcc6fc72 API to find pob in pob_manager 2018-06-27 22:49:35 -04:00
Arie Gurfinkel
5bc57238a6 Track whether pob is in pob_queue 
pob_queue is a priority queue. Changing a pob while it is in the queue might change
the priority. This is a source of subtle bugs. The flag is ment to help defend
against this issues in the future.

As a side-effect, a pob that is already in the queue will be silently not added
to it, and a new version of a pob might be created if a version being looked
for is already in the queue.

d9100437ce Weakness of the lemma independent of the pob 
Lemma inherits its weakness score from the pob. However,
pob's weakness might be reset or changed for some other reason.

To avoid affecting the lemma, the weakness is copied on
construction.
