A class to simplify adding items to a Bundle in Android. Multiple calls to the various put methods of the Bundle can be replaced with multiple calls to the single put method of this class, and a final call to wrap to return the finished Bundle.

For example, the following:

Bundle bundle = new Bundle();
bundle.putInt("myInt", 1);
bundle.putBoolean("myBoolean", true);
bundle.putDouble("myDouble", 2.2);
bundle.putString("myString", "Hello");

can be replaced with:

Bundle bundle = new Giftwrap()
      .put("myInt", 1)
      .put("myBoolean", true)
      .put("myDouble", 2.2)
      .put("myString", "Hello")
      .wrap();

Though the Bundle class has methods for adding ArrayLists of various types, all ArrayLists added via Giftwrap are added with Bundle.putSerializable and can be retrieved in their original form via the Bundle's various get methods for ArrayLists, such as Bundle.getIntegerArrayList. Similarly, Strings are added using Bundle.putCharSequence but can still be retrieved using Bundle.getString.
