get_area: Calculate geodesic area
In IceCast: Apply Statistical Post-Processing to Improve Sea Ice Predictions

Caclulate the geodesic areas of SpatialPolygons object on the Nothern Hemisphere Polar Stereographic grid projection

1	get_area(poly, byid = FALSE)

`poly`	`SpatialPolygons` object for which to calculate area
`byid`	boolean indicating whether areas should be calculated for each polygon individually or for the whole object together

Area calculations are for the Polar stereographic grid with major axis of 6378273m and ellipsoid flattening of 1/298.2794111.

Area of polygon (or vector of areas if byid is set to TRUE)
