A Sink with a First-In First-Out buffer
This buffer can always be written to, it overwrites any
data contained if needed
The class is not thread-safe
the buffer is filled like this:

|<---- valid data -------->|
outp inp
buffer bufferEnd

+----------------+--------------+--------------------+
-- valid data -->| |--- valid data ----->

Abstract :
Java-like object reference class
Objects used with this reference class have to be descandents
of class Referable
sample usage:
#include "Ref.h"
#include "Referable.h"
class A : public virtual Referable;
...
A * a = new A();
Ref<A> ref1 = a; // 1 reference to a
Ref<A> ref2 = ref1; // 2 references to a
ref1 = 0; // 1 reference to a
ref2 = 0; // at this point object a is destroyed
Based on Tima Saarinen's work,
