Version 0.5.8 not published

You are advertising version 0.5.8 but did not publish it on jitpack.

See for yourself:

You've forgotten to create the '0.5.8' tag :Ü™

Rounding issue in calculation of spherical law of cosines

I think I found a rounding issue in calculation of spherical law of cosines.

I have created a pull request for it (accompanied by unit-test) which sould explain this:

#23

I've modified my pom.xml to include the dependency as written in your README, but the jar file isn't in maven. The URL for http://repo.maven.apache.org/maven2/com/grum returns a 404 response. Has this code been moved elsewhere?

Issue with Bounding Area Calculation

BoundingArea area = EarthCalc.boundingArea(kew, 3000);
The boundingArea method does not exist it throws an error

Allow users to use geocalc through Jitpack

I wanted to suggest you to update the readme to offer developers to use geocalc through Jitpack.io

You can see that the project is already available so it might ease the integration process for developers, and for you avoid the culprit of submitting the project on Maven central.

I tried it on one of my local project, and it worked smoothly. You did a great job guys ;)

Compiler say's always method is not public

I wanted to use your lib but getting under JDK16/JDK17 always the following error message:
"toDMSCoordinate() is not public in Coordinate; cannot be accessed from outside package"

The lib is on the classpath and not on the modulepath.

How can I use it ?

Is the BoundingArea necessarily a rectangle ?

Can I set a BoundingArea area with a random shape, and use GeoCalc to determine whether a given Point is contained within that area ?

Distance calculation incorrect

The distance calculation is only correct for small distances.

import com.grum.geocalc.*;

public class Bug {
    public static void main(String[] args) {
        //Kew, London
        Coordinate lat = new DegreeCoordinate(51.4843774);
        Coordinate lng = new DegreeCoordinate(-0.2912044);
        Point kew = new Point(lat, lng);

        //Buenos Aires, as per wolframalpha.com
        lat = new DegreeCoordinate(34.61);
        lng = new DegreeCoordinate(-58.37);
        Point richmond = new Point(lat, lng);

        double distance = EarthCalc.getDistance(richmond, kew); //in meters 
        System.out.println(distance);
    }
}

As you can see in wolframalpha.com, it is supposed to be more than 11000 Km.
