add <nav> to the 'gulp uncss' task's ignoreArray in gulpfile.js
style the scrollNav HTML code (see message)
-center the <nav> links
-remove left padding
-add scrollNav-related links "grunt-uncss" ignoreArray in gulpfile.js
reset <ul> & <ol> tags in global.less...for now (see message)
Remove that extra 40x of padding-left that appears on all <ul> and<ol> tags. List those tags in the "grunt uncss" task's ignoreArray so the <ol> generated by scrollNav.js can be properly styled. May move this in  separate set/reset file for your custom CSS build that doesn't get ignored.
