Easily and flexibly insert 'Font Awesome' icons into 'R Markdown'
documents and 'Shiny' apps. These icons can be inserted into HTML
content through inline 'SVG' tags or 'i' tags. There is also a utility
function for exporting 'Font Awesome' icons as 'PNG' images for those
situations where raster graphics are needed.
