Simple master node created.
Worker sends heartbeat to master.
Docker containers can be run interactively.
Tests can be run using Makefile.
Worker sends information about its language model in heartbeat.
Basic logic of master implemented.
Workers are considered alive for 1 hour after the heartbeat.
Frontend asks Master for Worker's address.
Makefile refactored.
Gunicorn is used as a frontend server.
Frontend returns error when no worker is available.
