/***
 *
 * Purely static class used for interfacing with StudyGroup Server.
 * This class needs to be initialized once in order to begin.
 *
 * It is meant to run in its own thread, and must be provided a <QString, SGWidget*> pair
 * to notify a class of incoming events based on its QString key received from the server.
 *
 * Key formats **must** be consistent for this to work properly.
 *
 * Example: Incoming socket is a write to a whiteboard in biology_3485. This class will search
 * its internal dictionary for this: <QString("biology_3485 whiteboard"), Whiteboard*> and
 * add this message to the Whiteboard*'s work queue. The SGWidget*'s job is to interpret this message.
