Proposals that passed the threshold (finalized) can be cancelled by a minority again using the cancelProposal functions.
It only sets mapPID_votes to zero but mapPID_timeStart and mapPID_finalising stay the same and pass the checks in finaliseProposal which queues them for execution.
Proposals cannot be cancelled.
Recommend setting a cancel flag and check for it in finaliseProposal and in execution.
