testSphereSphere

Test whether the one sphere with center <code>centerA</code> and square radius <code>radiusSquaredA</code> intersects the other sphere with center <code>centerB</code> and square radius <code>radiusSquaredB</code>. <p> Reference: <a href="http://gamedev.stackexchange.com/questions/75756/sphere-sphere-intersection-and-circle-sphere-intersection">http://gamedev.stackexchange.com</a>

@param centerA the first sphere's center @param radiusSquaredA the square of the first sphere's radius @param centerB the second sphere's center @param radiusSquaredB the square of the second sphere's radius @return <code>true</code> iff both spheres intersect; <code>false</code> otherwise
