==Function: rotation llDetectedRot( integer number );==
Returns a rotation that is the rotation of detected object number. 
• integer number – Index of detection information 
number does not support negative indexes. 
Returns <0.0, 0.0, 0.0, 1.0> if number is not valid sensed object. 
'''Specification''' 
[[llDetected]]* functions can be called anywhere but will only return non-default values if called from within Detection events and functions called by Detection events. 
'''Caveats''' 
• Events that enable the [[llDetected]]* functions always return at least one detected item. 
-• Detection events are not raised if there is nothing detected (with the slight exception of no_sensor but it doesn't enable [[llDetected]]* functions). 
-• The event detection count parameter value is initially never less than 1. 
'''Examples'''
