CVS commit by netterfield: 

Add getIndexNearX(x) to kstbasecurve, which looks for the index near x.
If the curve is monotonically rising, it uses a binary search.  Otherwise,
it uses a linear search.

Then use this function to re-do dataMode....

It works - in that it does what I though I wanted it to do...
