   SVG to CSS Example: Breadcrumbs "Home Icon"
   - an example of using the Open Iconic SVG code to create a "home" icon
   - this is the same method as used in the Bootstrap 4 _variables.sccs file
   - started by downloading the distro from https://useiconic.com/open
   - found the 'home' icon SVG and copied its path code
   - then pasted the path code into one of the Bootstrap icon definitions &
     changed the fill color
