Formula occurrence factory.
Formula occurrence factory. This factory is stored in FormulaOccurrence itself, sometimes passed via an implicit
factory
parameter, or directly linked to defaultFormulaOccurrenceFactory.
Specialized factories can return instances of subclasses of FormulaOccurrence, e.g. at.logic.gapt.proofs.lksk.LKskFOFactory.
FIXME: The only supported factory is defaultFormulaOccurrenceFactory at the moment.

A formula occurrence is an occurrence of a HOLFormula in a proof.
A formula occurrence is an occurrence of a HOLFormula in a proof. Both formulas in different sequents and multiple occurrences of the same formula (e.g. introduced by contraction) have a different FormulaOccurrence.
Creates instances of FormulaOccurrence.
Implicitly converts a FormulaOccurrence to the formula its occurrence it records.
