Notes for Technically inclinded.  

1. The "End of lesson" will be used if no "End of Branch" or "End Cluster" 
page can be found in the logical order.  

For example a jump choice is "Unseen question in Cluster".  
Lesson will look for the "End of Cluser" page as one of its conditions.  
It's search starts with its current page  and looks towards the end of the lesson in the logical order. 
It will not accept an "End of Cluster" that appears towards the start of the lesson 
from its current position in the logical order.
