fix the issue by connecting to the dataengine from within the python code
rather than the QML?  Perhaps the conflict is coming from the fact that if
the python is the logic and QML is the code, then I can't be accessing the
data engine from within the QML.  If that's the case, how would I pass the
data from python into the QML so that the QML can take care of layouts.  OR
would I just do the data engine connection as javascript to bypass the
import of org.kde.plasma.core?
