                                      Balloon c2,
                                      Balloon c3,
                                      int s1,
                                      int s2,
                                      int s3)

Solves the Problem of Apollonius (finding a circle tangent to three other circles in the plane). The method uses approximately 68 heavy operations (multiplication, division, square-roots).

Parameters:

c1 - One of the circles in the problem

c2 - One of the circles in the problem

c3 - One of the circles in the problem

s1 - An indication if the solution should be externally or internally tangent (+1/-1) to c1

s2 - An indication if the solution should be externally or internally tangent (+1/-1) to c2

s3 - An indication if the solution should be externally or internally tangent (+1/-1) to c3

Returns:

The circle that is tangent to c1, c2 and c3.
