示例1: collidesWithWeatherDataSet
/**
\brief test if the radius r ball centered at current node conflict with the weatherdata
This only does 2d testing if their z coordinates collide with each other
This routine has been updated from treating weather data as the lower left corners
of cellWidth*cellWidth squares. Now they are circles of radius cellWidth.
This returns true if any weather with a deviationProbability >= thresh is closer
than r to any points in the weather ensemble wData.
\param r Radius of node i.e. how far node must be from edge of weather.
\param WeatherData A single weather ensemble.
\param thresh Minimum deviationProbability for a weather cell to be dangerous
