// Super sweet focus behavior for textboxes!
// clears out & replaces hint text in form textbox fields on focus
// put initial value back in if user blurs & hasn't entered new value
// ex: <input type="text" value="initial value" class="efHoverImage" />
// when called: $().efTextboxFocus(); will automatically set up focus behavior on all inputs with class .efTextboxFocus
// or can call function on specific element(s) $('.selector').efTextboxFocus();
