functional: Change order of two classes
functional: Change order of two classes

We want the 'IntegratedHelper' class to use the 'InstanceMixin' mixin
class. This is currently not possible because the latter is defined
after the former.  This patch moves the class definitions around,
allowing us to do this in a future change when we've unified the
behavior of some competing functions provided by either.
