  Generate a grid navigation item into a given array. A grid navigation item is presented by a wrapper object wrapping the domNode.
  
  @param {Array} domNodeWrapperList the array that holds the grid navigation item. Normally the .gridChildren property from a row model.
  @param {Element} element the html dom element representing a grid. Normally left or right arrow keys on the current row highlight the dom element.
  When a grid is rendered, the caller has to decide what dom element can be passed.
