CLASSES
    __builtin__.object
        HilbertCurve
            HilbertContainer
    
    class HilbertContainer(HilbertCurve)
     |  A container that can be indexed along either the 1- or 2-dimensional aspects
     |  of a Hilbert curve.
     |  
     |  Indexing by the 1-dimensional distance is done just like indexing into a list: curve[d]
     |  
     |  Indexing by 2-dimensional coordinates works the same way: curve[x,y]
     |  
     |  For example:
     |  
     |  >>> curve = HilbertContainer(8)
     |  >>> curve[3] = "example"
     |  >>> curve.d2xy(3)
     |  (1, 0)
     |  >>> curve[1,0]
     |  'example'
     |

     |  __init__(self, side_length, empty=None)
     |  
     |  __iter__(self)
     |      Generator for iterating over the curve. Yields a 2-tuple of (x, y)
     |      and the value at that point, in Hilbert-curve order (a la turtle).

    class HilbertCurve(__builtin__.object)
     |  Object-oriented interface to 2-dimensional Hilbert curves.
     |  
     |  A HilbertCurve object has one attribute, *side_length*, which is the square of
     |  the order of the curve. A third-order Hilbert curve has a side length of 2**3, or 8.
     |  The side length will be coerced into the next highest positive power of 2.

        which fills a square *side_length* units on a side.
