 #### c_forrange
 Declare an iterator and specify a range to iterate with a for loop. Like python's ***range()*** function:
-- c_forrange (stop)                              #  for _ in range(stop):
-- c_forrange (i, stop)  // IterType=size_t       #  for i in range(stop):
-- c_forrange (i, IterType, stop)                 #  for i in range(stop):
-- c_forrange (i, IterType, start, stop)          #  for i in range(start, stop):
-- c_forrange (i, IterType, start, stop, step)    #  for i in range(start, stop, step):
