Finite Mass

[ghost]

In the book (p 47) it says the inverse mass is used for representing infinite mass

.. objects of infinite mass have a zero inverse mass

but the code in particle.cpp reads

bool Particle::hasFiniteMass() const
{
    return inverseMass >= 0.0f;
}

causing the bug

setInverseMass(0); hasFiniteMass() == true

agreed, probably best would be to check if inverse mass is equal to zero (of course using a bias to compensate for numerical precision). I will try to fix this and make a pull request.
