Operator: find-pagenum

Operator Overview:

The find-pagenum operator is used to scan the page for the page number. Among other things, this allows us to determine whether this is a left-side page or a right-side page, so that we know how to flip to the next.

Operator Proposal:

The operator is proposed when one has reached the bottom of the page while searching for a step.

Operator Application:

This operator is implemented by the scan-page problem-space.

Operator Reconsider:

An operator proposal is returned, which causes the impasse to terminate.
