Crates buffered function

underscore-ext.js

// Calls a function only once within the given wait time. Last call is
// considered, which is the difference between from _.throtle
//
_.buffer = function(func, wait, scope) {
  var timer = null;
  return function() {
    if(timer) clearTimeout(timer);
    var args = arguments;
    timer = setTimeout(function() {
      timer = null;
      func.apply(scope, args);
    }, wait);
  };
};

Note, you can use _.debounce for this now.
