How to load external stylesheets such as for Google Icons - https://www.w3schools.com/icons/google_icons_intro.asp or Font-Awesome https://www.w3schools.com/icons/fontawesome_icons_intro.asp.
As per the instruction the <link> tag has to go inside the head of the web page(s), but I can't find out which page in Machform this should be. Also, should this go in the "head" of the page in which Machform is embedded or in to a file within the Machform application itself?
