Holds a list of objects derived from ReferenceCountedObject, or which implement basic reference-count handling methods.
The template parameter specifies the class of the object you want to point to - the easiest way to make a class reference-countable is to simply make it inherit from ReferenceCountedObject or SingleThreadedReferenceCountedObject, but if you need to, you can roll your own reference-countable class by implementing a set of methods called incReferenceCount(), decReferenceCount(), and decReferenceCountWithoutDeleting(). See ReferenceCountedObject for examples of how these methods should behave.
A ReferenceCountedArray holds objects derived from ReferenceCountedObject, and takes care of incrementing and decrementing their ref counts when they are added and removed from the array.
To make all the array's methods thread-safe, pass in "CriticalSection" as the templated TypeOfCriticalSectionToUse parameter, instead of the default DummyCriticalSection.

If the index is less than 0 or greater than the size of the array, the element will be added to the end of the array. Otherwise, it will be inserted into the array, moving all the later elements along to make room.

Inserts a new object into the array assuming that the array is sorted.

Removes a range of objects from the array.
This will remove a set of objects, starting from the given index, and move any subsequent elements down to close the gap.
If the range extends beyond the bounds of the array, it will be safely clipped to the size of the array.

Swaps a pair of objects in the array.

noexcept |
Moves one of the objects to a different position.
This will move the object to a specified index, shuffling along any intervening elements as required.
So for example, if you have the array { 0, 1, 2, 3, 4, 5 } then calling move (2, 4) would result in { 0, 1, 3, 4, 2, 5 }.
| currentIndex | the index of the object to be moved. If this isn't a valid index, then nothing will be done |

Reduces the amount of storage being used by the array.
Arrays typically allocate slightly more storage than they need, and after removing elements, they may have quite a lot of unused space allocated. This method will reduce the amount of allocated storage to a minimum.

Increases the array's internal storage to hold a minimum number of elements.
Calling this before adding a large known number of elements means that the array won't have to keep dynamically resizing itself as the elements are added, and it'll therefore be more efficient.
