SVG Sprites are a slightly more advanced method of combining your icons into a single SVG file - but there are a number of benefits to this method. To read more about SVG Sprite, see https://css-tricks.com/svg-sprites-use-better-icon-fonts.
SVG Sprites should be placed in the root of your
iconSetsPath folder and have the suffix of
-sprites.svg. This will be so we can differentiate it between single SVG icons.
