* Split deletePastBlocks into sub-routines * Remove SelectedParentIterator, and refactor SelectedChildIterator to support First and Error * Implement PruneAllBlocks * Prune all blocks in the store * Prune only blocks that are below the pruning point * Defer call onEnd of LogAndMeasureExecutionTime * Handle a forgotten error * Minor style fixes
