Calculate cardinal direction distances between two coordinates

[LeoVie]

Given you have two Coordinates:

• Point1 at (51.049531, 13.720699)
• Point2 at (51.069706, 13.775459)

you'd like to know the shortest possible right angle to reach the Point2 from Point1

This would be possible by determining the point in the NorthWest corner (Point3) and calculate the distances Point1<->Point3 and Point2<->Point3.

As the sortest possible distances should be calculated, there has to be a check before: If Point1 is in NorthWest of Point2, the shortest directions are to go south and east.

Point1 in reference to Point2	Directions
North	South
East	West
South	North
West	East
NorthWest	South, East
NorthEast	South, West
SouthWest	North, East
SouthEast	North, West

The only real new logic would be this determination. The determining of Point3 could be done via the class Bounds, the calculation of the distances via the class Coordinate.

What do you think about this feature? If something is unclear, please ask me. :)

That sounds like it's a useful feature which should be relatively easy to implement :-)

Nice, I'll implement it in the next days.
