====== VectorAngle ======
VectorAngle(<-from <-to) ->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.
NOTE: This routine does NOT work with 4 dimensional vectors.  The 4th dimension will be ignored (treated as 0).

===== Examples =====
<code 4rpl>
trace(VectorAngle(V3(1 2 3)  V3(3 4 5)))
