DenseNodes

Used to densly represent a sequence of nodes that do not have any tags. We represent these nodes columnwise as five columns: ID’s, lats, and lons, all delta coded. When metadata is not omitted, We encode keys & vals for all nodes as a single array of integers containing key-stringid and val-stringid, using a stringid of 0 as a delimiter between nodes.
