Semicircles flipping coordinates

[samuelmr]

Running the following code (using Semicircles)

var myLocation1 = new Position.Location({
  :latitude => 38.856147,
  :longitude => -94.800953,
  :format => :degrees});
var mySC1 = new Semicircles.Coordinate(myLocation1);
System.println(myLocation1.toRadians());
System.println(mySC1.toRadians());

outputs

[0.678168, -1.654589]
[-0.678168, 1.654589]

Note that the signs of the coordinates are flipped. Is this somehow intentional?

It seems that the sign-flipping is consistent: in my tests negative values are always turned positive and vice versa.
