/* arg : The data-filter to parse for sorting. In our case it would be “data-category”
sel : This will be the parent selector that contains the data filter. In our case it is the class “search-results”
elem : This further narrows down the child elements within the parent selector, which is just a “li” in this case
order : This specifies the sort order. “asc” or “desc” would either be acceptable *\
