Emulates 'mouseenter' and 'mouseleave' on a group of contiguous elements as if they were only one.
Works both required as CommonsJS module (e.g., to bundle it with Browserify) in node or in the browser.
/**

*
* @param {Element[]} elems Group of contiguous Elements.
*
* @param {Function} onEnter Called when mouse enters the
* group of elements.
*
* @param {Function} onLeave Called when mouse leaves the
* group of elements.
*
* @param {Boolean} [exclusive] If true, element groups cannot
* be hovered simultaneously. This
* means that in groups with elems
* in common, it won't notify all
* groups when entering or leaving
* the common elem, only the group
* defined in the first place. It
* defaults to false.

}As a CommonsJS module it exports a function, and in a browser environment declares mergedHoverEvents() function in the global scope.
