Added helpers to access objects while creating the flatbuffer.
Added helpers to access objects while creating the flatbuffer.

GetObject and GetMutableObject are similar to GetRoot and GetMutableRoot,
and can be useful when wanting to access data that has just been created.
Unfortunately there is a danger in using these methods, as it is possible
that the buffer reallocates which will invalidate the pointers.
