## Cluster Manager Interface

This interface provides a mechanism to launch and manage Julia workers on different cluster environments.
There are two types of managers present in Base: `LocalManager`, for launching additional workers on the
same host, and `SSHManager`, for launching on remote hosts via `ssh`. TCP/IP sockets are used to connect
and transport messages between processes. It is possible for Cluster Managers to provide a different transport.
