/*
    Helper class that automates refernce counting for CFtypes.
    After constructing the QCFType object, it can be copied like a
    value-based type.

    Note that you must own the object you are wrapping.
    This is typically the case if you get the object from a Core
    Foundation function with the word "Create" or "Copy" in it. If
    you got the object from a "Get" function, either retain it or use
    constructFromGet(). One exception to this rule is the
    HIThemeGet*Shape functions, which in reality are "Copy" functions.
