====== VectorAngleCell ======
VectorAngleCell(<-fromX <-fromZ <-toX <-toZ) ->rotAngle

===== Description =====
Returns the angle in degrees between from and to.
The angle returned is always the non reflex angle between the two vectors - ie the smaller of the two possible angles between them and never greater than 180 degrees.

===== Examples =====
<code 4rpl>
trace(VectorAngle(1 2 3 4 ))
