  KK.type(true) // 'number'
  KK.type(new Date) // 'date'
  KK.type(function(){}) // 'function'
  KK.type(null) // 'null'
  KK.type(undefined) // 'undefined'
  KK.type(new Object) // 'object'
  KK.type(NaN) // 'nan'

• KK.isString(arg)

• KK.isBoolean(arg)

• KK.isDate(arg)

• KK.isUndefined(arg)

• KK.isObject(arg)

• KK.isNaN(arg)

• KK.isJSONString(arg)

  KK.isJSONString('{"name" : 'obama'}') // true
  KK.isJSONString(3) // false

• KK.isEmptyObject(arg)

  KK.isEmptyObject({}) // true
  KK.isEmptyObject({'name' : 'Obama'}) // false

• KK.each(collection, callback)

  • collection {array | json}
  • callback {function} When callback return false, loop will break.

  var a = [11, 22, 33, 44]
  KK.each(a, function(item, index, context){
    if(item > 22){
      return false;
    }
    // 33 and 44 will not print
    console.log(item);
  })

• KK.queryString(arg) Got key-value params from urls.

    var a = 'name=lily&age=2&grade=3';
    // Got {'name' : 'lily', 'age' : 2, grade : 3} 
    KK.queryString(a) 
  	

• KK.merge(target, source)

  var target = { a : 1, read : {book : true}, count : [11]}
  var source = { a : 2, read : {paper : true, book : false}, count : [1]}
    
  // Got { a : 2, read : {book : false, paper : true}, count : [1] }
  KK.merge(target, source); 
  console.log(target.read === source.read); // true

• KK.deepMerge(target, source)

  var target = { a : 1, read : {book : true}, count : [11]}
  var source = { a : 2, read : {paper : true, book : false}, count : [1]}
    
  // Got { a : 2, read : {book : false, paper : true}, count : [1] }
  KK.merge(target, source); 
  console.log(target.read === source.read); // false
