Update Dataset interface to be fully compliant with new generic Tuple data

It appears to me that with the introduction of tuples, the Dataset interface 
needs to be upgraded.

 Currently, there is an implicit assumption that there is only one Y value, and hence, one range 
label, one axisid,  one set of rangetop/bottom, etc. However, this is not true 
with tuples. For 
example, with a time/open/high/low/last tuple5, the axisid might be all the 
same (same units, 
e.g. $), but the labels would obviously be different. For bubble charts, the 
bubble radii axis 
would have different units and labels. Take a look at Google's MotionChart for 
example: 
http://code.google.com/apis/visualization/documentation/gallery/motionchart.html

There is a time domain, as well as 3 separate range labels and unit types. One 
for X, one for Y, 
and one for the radius. You could have GDP ($), Life Expectancy (yrs), and 
Population (ppl).
