 * \brief  Janus core
 * \details Implementation of the Janus core. This code takes care of
 * the server initialization (command line/configuration) and setup,
 * and makes use of the available transport plugins (by default HTTP,
 * WebSockets, RabbitMQ, if compiled) and Janus protocol (a JSON-based
 * protocol) to interact with the applications, whether they're web based
 * or not. The core also takes care of bridging peers and plugins
 * accordingly, in terms of both messaging and real-time media transfer
 * via WebRTC.
