base_object::check_collision() should take an object pointer.

[Rick Stovall]

in /cpp/sim_engine/base_object/base_object.[h|cpp] :

bool base_object::check_collision(sphere s)
{
  float r = s.radius + bounding_sphere.radius;
  return r <=
    s.center.range(bounding_sphere.center+location);
};

This method should take an object_p (a pointer to an object) instead of a sphere; this will greatly simplify collision checks.

Fixed... found an additional issue where the method was returning an inverted truth table (discovered during unit test).
