        • Router - The module responsible for routing, ie. navigating through the pages (components) of the application.
        • Planner - A specially designed module that manages the Component Planner, it was separated due to the use of "CalendarMonthViewComponent" which contains a class for working with the calendar that is different from the built-in (used in the App) module, thus resolving the conflict.

NOTE: Application uses DialogFlow Messanger for smart agent, necessary steps to setup is as follows:
    1. Start the webhook server located on the path /src/app/bot-backend by entering the command "node index.js" (note the required node module packages are already in the folder). The webhook operates on port 21683.
    2. Activate ngrok (https://ngrok.com/) by entering the command ngrok http 21683. (Note to use ngrok you need to have account, you can use your Google or GitHub).
    3. Import the smart agent dialogflow using the Smart_Agent_Dialogflow_Export.zip file to your dialogflow account.
    4. Enter the https link obtained by ngrok as the Fulfillment Webhook URL.

Note: It is possible that the webhook server will stop working after entering a few messages for a reason unknown to me, in which case it is enough to restart webhook server.
