Fix OnTouchEvent for GraphicalView

[GoogleCodeExporter]

What steps will reproduce the problem?

1. setOnTouchListener() to a View.OnTouchListener implementation
2. Inside the OnTouchListener implementation, get a SeriesSelection by calling 
GraphicalView.getCurrentSeriesAndPoint()
3. The SeriesSelection returned is always null

What is the expected output? What do you see instead?

The SeriesSelection returned should not be null but should work like it would 
if it was in an OnClickEvent. Apparently ACE uses OnTouchEvent internally which 
causes a problem for calling client code.

chart.setOnTouchListener(new View.OnTouchListener()
{
    @Override
    public boolean onTouch(View v, MotionEvent event)
    {
        SeriesSelection seriesSelection = chart.getCurrentSeriesAndPoint();

        if(seriesSelection == null)
        {
            Log.d(TAG, ":(");
        }

        return true;
    }
});

What version of the product binary library are you using?

1.0.0

Use setOnClickListener. See an example here:
