class LCDRange < Qt::Widget

For a case such as the above, the QWidget can't be instantiated until
the initializer has been run up to the point where 'super(parent, name)'
is called. Only then, can the number and type of arguments passed to the
constructor be known. However, the rest of the intializer
can't be run until 'self' is a proper T_DATA object with a wrapped C++
instance.

The solution is to run the initialize code twice. First, only up to the
'super(parent, name)' call, where the QWidget would get instantiated in
initialize_qt(). And then rb_throw() jumps out of the
initializer returning the wrapped object as a result.

The second time round 'self' will be the wrapped instance of type T_DATA,
so initialize() can be allowed to proceed to the end.
