abstract class FormulaTask extends PrioritisedTask

The representation of formulas in a proof goal that are more complex than simple facts. Such formulas are considered to have positive polarity, i.e., as conjunctions in the succedent of a goal. This class is both responsible for storing such formulas and for eventually processing the formulas, e.g. by splitting up the formulas/proof goal.
