A smart-pointer class which points to a reference-counted object.
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.
When using this class, you'll probably want to create a typedef to abbreviate the full templated name - e.g.

Destructor.
This will decrement the object's reference-count, which will cause the object to be deleted when the ref-count hits zero.

Returns the object that this pointer references.
The pointer returned may be null, of course. Note that this methods allows the compiler to be very lenient with what it allows you to do with the pointer, it's safer to disable this by setting JUCE_STRICT_REFCOUNTEDPOINTER=1, which increased type safety and can prevent some common slip-ups.
