      Concatenate two Iterable sources
      Type Parameters:
        `T` - the value type

      Type Parameters:
        `T` - the value type
      Parameters:
        `a` - a non-null Iterator
        `b` - a non-null Iterator
      Returns:
        an Iterator that will iterate through all the values of 'a', and then all the values of 'b'
