North with lsl

[Cinder Darkheart]

What would be the best way to handle setting a prim to face north? Not looking to make a compass just need to force the prim to face north on rez on calls of an update.

1. Determine and define which direction is the object's "front."
   You can, for example, use a vector like <1, 0, 0> (meaning positive X is forward) and account for the object's current rotation.

2. Get the rotational difference between the object's front and "north." (Positive Y, probaby.)

3. Rotate by that amount.
