-step~  : will make a unity step at a desired point in the signal-vector; the second input specifies a 
-			length:	after the so-specified time has elapsed, the step will toggle back to the previous
-			value;
-			the length can be passed as an argument when creating the object
-			with length==1 you might do the dirac~ thing a little bit more complicated
-			with length==0 the output just toggles between 0 and 1 every time you bang the object
-
-NOTE : the inlets do NOT specify any times but sample-NUMBERS; there are 64 samples in a signal-vector,
-		each "lasting" for 1/44100 secs.
