updated readme with ominous warning
closes #68 - also rearranged the section on rollovers to include more examples
made a first stab at some of the boilerplate for scatterplots - no rollovers yet, however
yep forgot to add data
added first bit of rollover functionality. No text quite yet - its clear that we need to separate out some of the text-generating functions in the line rollover for reuse.
added slightly different styling to scatter, a la R
see-saw back and forth between unselected being more transparent
