// Workflow:
// We first spin up an empty handler, that can connect to a server, and create a client.
// We then use the client, to login into a workspace, and join it, obtaining a workspace object
// We will then use that workspace object to interact with the buffers in that workspace.
// In steps:
// 1. Get Object that can initiate a connection
// 2. Connect to a server
// 3. Login to a workspace
// 4. Join a workspace/get an already joined workspace
// 5. Create a new buffer/attach to an existing one
