        Given an array BObject, returns the item at the given index. In the case that the array contains elements of primitive type (int etc.), the return value is of the appropriate Java wrapper type (Integer etc.). In the case that the array is composed of BlueJ objects (including nested arrays) then an appropriate BObject will be returned.
        Parameters:
        thisArray - a array BObject to retrieve the specified item of.
        itemIndex - the index of the BArray's item to retrieve.
        Returns:
        An Object that encapsulate the specific item or null if thisArray is not an array.
        Throws:
        ProjectNotOpenException - if the project to which this array belongs has been closed by the user.
        PackageNotFoundException - if the package to which this array belongs has been deleted by the user.
