class Point(object):
    """
    A geodetic point with latitude, longitude, and altitude.
    
    Latitude and longitude are floating point values in degrees.
    Altitude is a floating point value in kilometers. The reference level
    is never considered and is thus application dependent, so be consistent!
    The default for all values is 0.
    
    Points can be created in a number of ways...
        
    With longitude, latitude, and altitude:
    >>> p1 = Point(41.5, -81, 0)
    >>> p2 = Point(latitude=41.5, longitude=-81)
    
    With a sequence of 0 to 3 values (longitude, latitude, altitude):
    >>> p1 = Point([41.5, -81, 0])
    >>> p2 = Point((41.5, -81))
    
    Copy another `Point` instance:
    >>> p2 = Point(p1)
    >>> p2 == p1
    True
    >>> p2 is p1
    False
    
    Give an object with a 'point' attribute, such as a `Location` instance:
    >>> p = Point(location)
    
    Give a string containing at least latitude and longitude:
    >>> p1 = Point('41.5,-81.0')
    >>> p2 = Point('41.5 N -81.0 W')
    >>> p3 = Point('-41.5 S, 81.0 E, 2.5km')
    >>> p4 = Point('23 26m 22s N 23 27m 30s E 21.0mi')
    >>> p5 = Point('''3 26' 22" N 23 27' 30" E''')
    
    Point values can be accessed by name or by index:
    >>> p = Point(41.5, -81.0, 0)
    >>> p.latitude == p[0]
    True
    >>> p.longitude == p[1]
    True
    >>> p.altitude == p[2]
    True
    
    When unpacking (or iterating), a (latitude, longitude, altitude) tuple is returned
    >>> latitude, longitude, altitude = p
