Cards: Create, Update, Delete robots
Need to able to publish into relevant topics

Issue:
Uncaught DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document

Update: This only happens in the local environment

The app supposes to run on the 'http://pera-swarm.ce.pdn.ac.lk/swarm-admin' URL, but once it visits the page, the URL in the browser will automatically be changed into 'https://pera-swarm.ce.pdn.ac.lk/home'.

Need React Component implementations for Publish and Subscribe components as in MQTTBox software.

• Publisher: Topic (textbox), MessageBox (textarea), Publish (Button)
• Subscriber: Topic (textbox), MessageBox (p), Subscribe/Unsubscribe (Button)

Please make sure to implement the component by taking less space in the window.
It is better if we can pass the default topic, message body as attributes of the component within brackets

The purpose of this is to demonstrate the functionality and debugging.

• Textbox is not accepting negative coordinates, please fix
• Need to publish to 'v1/localization/info' once the robot is created and coordinates or heading slider changed.
