This class determines whether it is possible to create an array of type T. If it is not, and T is not void, a reference, or a function, it assumes that T must be an abstract base class. The problem is that it is impossible to create an array of any type that does not have a public constructor, for instance a non-abstract singleton class. So this does not quite work.
