To run the server:
$ gradle runIf running as root, the databases will be stored in /var/zerograph by
default. For other users, the $HOME/.zerograph directory will be used.
These defaults can be overridden using the ZG_STORAGE_PATH environment
variable.
The default database instance listens on port 47474.
To run the Python test shell:
$ pip3 install pyzmq
$ cd src/client/python
$ python3 -m zerograph.repl
