---------------------------------

             Summary: Add ZigZag encoding/decoding algorithm
                 Key: IOTDB-2461
                 URL: https://issues.apache.org/jira/browse/IOTDB-2461
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Yuting Yan


[ZigZag|https://gist.github.com/mfuerstenau/ba870a29e16536fdbaba] encoding maps signed integer/long data to unsigned integer/long data so that numbers with a small absolute value (for instance, -1) have a small variant encoded value too. It does this in a way that "zig-zags" back and forth through the positive and negative integers.
