[LON-CAPA-dev] Conditional branching and 1.99.2

Sounds to me like things are workign correctly and you haven't built
the map correctly.

For instance

A - Exp.
B - Exam
1 - condition

If you have

Start -> A -> B -> End

And A is
Start -> ThingA -1-> ThingB -> End


Then what you really have is

Start ->  ThingA -1-> ThingB -> B -> End


And thus you can't see B, because there is no valid path to B that
doesn't involve the condition being true.

What you really want in your map is:

Start ---> A -----> End
       \      /
        -> B -

(You don't really want a linear map anymore...)

Or you want A it be:

Start --->  ThingA -1-> ThingB -> ---> End
        \                         /
         -------------------------
