See http://stackoverflow.com/questions/2062560/what-is-the-use-of-making-constructor-private-in-a-class
answer 63 for a good summary.  Or maybe Google something like "C++ design patterns"
for the full story.

In QSP, I guess having a class allows you to qualify names of static "simple functions" and
enums by using the name of the class and having a private ctor with no implementation
ensures that you cannot create a QSP object, copy a QSP object or inherit from the class.

Cheers, Ian W.
