As an user I would like to have access to a set of commands that will allow me to save and/or cancel a function.

Acceptance criteria:

• Add a new component in the editor to handle the function command
• If the user clicks "cancel" navigate to the "special:CreateObject" page
• if the user has not completed all the required information the publish and write implementation button are greyed out
• if the user has completed all the enquired steps the buttons are enabled
• if the user loads an existing function (function editing), or has just published a function, the first button shows the word "published!"
• if the user makes any change to the function since load or since publishing, the button will change to "publish"
• If the user Clicks "publish" the UI will save the function and provide a visual UI (green toast) to congratulate the user
