To run gStore, please type `bin/gload database_name dataset_path` to build a database named by yourself. And you can use `bin/gquery database_name` command to query a existing database. What is more, `bin/gconsole` is a wonderful tool designed for you, providing all operations you need to use gStore. Notice that all commands should be typed in the root directory of gStore.
