recursive procedure which adds elements from elements_ to the current block, ie blocks_->back(). the resulting links between elements are stored in links, not in the block. afterwards, packLinks( reco::PFBlock& block, const vector<PFBlockLink>& links) has to be called in order to pack the link information in the block.
