---------------------------------
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.
