-/**
-* This fixes `$(...).attr()` to work as expected with SVG elements.
-* Does not currently use `*AttributeNS()` since we rarely need that.
-* Adds {@link external:jQuery.fn.attr}.
-* See {@link https://api.jquery.com/attr/} for basic documentation of `.attr()`.
-*
-* Additional functionality:
-* - When getting attributes, a string that's a number is returned as type number.
-* - If an array is supplied as the first parameter, multiple values are returned
-*    as an object with values for each given attribute.
-* @function module:jQueryAttr.jQueryAttr
-* @param {external:jQuery} $ The jQuery object to which to add the plug-in
-* @returns {external:jQuery}
