/** An array designed for holding objects.

    This holds a list of pointers to objects, and will automatically
    delete the objects when they are removed from the array, or when the
    array is itself deleted.

    Declare it in the form:  OwnedArray<MyObjectClass>

    ..and then add new objects, e.g.   myOwnedArray.add (new MyObjectClass());

    After adding objects, they are 'owned' by the array and will be deleted when
    removed or replaced.

    To make all the array's methods thread-safe, pass in "CriticalSection" as the templated
    TypeOfCriticalSectionToUse parameter, instead of the default DummyCriticalSection.
