a demo for issues: neo4j/neo4j#12551
neo4j的bolt使用json格式进行数据传输，显然json是一种低效的方式，这个demo用json和protobuffer做比较，演示json有多慢
The BOLT of Neo4j use JSON for data transmission, obviously JSON is an inefficient way, and this demo shows how slow JSON is by comparing it with the ProtoBuffer
运行src\main\java\com\bolttest\server\StartUpServer.java，将启动一个Neo4j，并注册两个自定义存储过程test.topo和test.topopb，
这两个存储过程都是返回100000条测试数据，只是test.topopb用protobuffer套了个壳
随后，运行src\test\java\com\bolttest\client下的两个测试类，观察运行耗时，可发现test.topopb快了10倍
Run src\main\java\com\bolttest\server\StartUpServer.java will launch a Neo4j and register two custom stored procedures' test.topo 'and' test.topopb ',
Both of these stored procedures return 100,000 test data, but with a shell called ProtoBuffer for test.topopb
Then, run the two test classes under src\test\java\com\bolttest\client,
and observe that the run takes time, you can find that 'test.topopb' is 10 times faster
