// Event handling with jQuery
//
// Step 1
//
// Set up event handler(s) for div.item elements so that:
// on mouseover, the "hover" class is added AND the img "src" attributed is logged to the console
// on mouseout, the "hover" class is removed
// on click, the div is hidden (hint: hide())
// Step 2
//
// All done? Did you delegate?
// If not, set it up so that you are delgating
// event handling to the wrapper div
