/**
* \class GeographicalDistance
* \brief Compute the metric distance between two geographical points
*
* Vector length must be at least two, otherwise the Evaluate method
* will throw an exception.
*
* First dimension is assumed to be the longitude, and second
* dimension is assumed to be the latitude.
*
* This distance uses the Haversine formula, which can be found here:
* http://www.movable-type.co.uk/scripts/latlong.html
*
* Please note that the computation makes use of the earth radius in
* meters. Mean radius (6371 km) is used as a default value, but one
* might use local values from spheroid or geoid for better precision.
