+SERVER_CLIENT_MESSAGE_PROTOCOL
+NOTE: clients always send game id and their id
+      when creating sockets (via socket.protocol), so
+      this doesn't need to be set in each message data
+
+NOTE: first value in the array is always the type of event/message
+      when describing them below, the value each has is used
+      instead of writing EVENT_TYPE or something ismilar
+
+
+EV_CLIENT_EVENT: event triggered by clients and sent to server
+[
+  EV_CLIENT_EVENT, // constant value, type of event
+  CLIENT_SEQ, // sequence number sent by client.
+  EV_DATA, // (eg. mouse input info)
+]
+
+EV_SERVER_EVENT: event sent to clients after recieving a client
+                 event and processing it
+[
+  EV_SERVER_EVENT, // constant value, type of event
+  CLIENT_ID, // user who sent the client event
+  CLIENT_SEQ, // sequence number of the client event msg
+  CHANGES_TRIGGERED_BY_CLIENT_EVENT,
+]
+
+EV_CLIENT_INIT: event sent by client to enter a game
+[
+  EV_CLIENT_INIT, // constant value, type of event
+]
+
+EV_SERVER_INIT: event sent to one client after that client
+                connects to a game
+[
+  EV_SERVER_INIT, // constant value, type of event
+  GAME, // complete game instance required by
