 ## Function: init_db
 - Initializes the SQLite database.
-- Creates two tables: logs and boards.
+- Creates four tables: logs, boards, mir_server_missions, and requested_missions.
 - The logs table stores log entries with timestamp, hostname, IP address, and message.
 - The boards table stores the status of each board with hostname, IP address, and status of inputs and relays.
+- The mir_server_missions table stores the information required to create a JSON post for a mission.
+- The requested_missions table stores the response data from the mission post request.

+## Function: post_mission
+- Sends a mission post request to the MIR server.
+- Retrieves the IP, authorization, username, and password from the mir_server_missions table.
+- Formats the headers and sends a POST request to the mission scheduler endpoint.
+- Prints the result of the mission post request.
