/*
Spline_Trans(Spline, Time, SkyVector, ForeSight, Banking)

This macro aligns an object to a spline for a given time value. The Z axis of 
the object will point in the forward direction of the spline and the Y axis of 
the object will point upwards.
Parameters:

Spline = The spline that the object is aligned to.
Time = The time value to feed to the spline, for example clock.
Sky = The vector that is upwards in your scene, usually y.
Foresight = A positive value that controls how much in advance the object will 
turn and bank. Values close to 0 will give precise results, while higher values 
give smoother results. It will not affect parsing speed, so just find the value 
that looks best.
Banking = How much the object tilts when turning. The amount of tilting is 
equally much controlled by the ForeSight value.
Usage:

   object {MyObj Spline_Trans(MySpline, clock, y, 0.1, 0.5)}
