bolt-chapter-listitems-hierarchical

{#  for Bolt.cm
    Situation: A chapter contains an undefined amount of items, either with typefield "A" or with typefield "B" 
    (two  "levels"). Print these items out in a hierarchical menu with nested ul's (2 levels deep as per "A" and "B"
    If you need more levels, add -for instance- "C" and add extra checks in the code
    
    Goal:
    Go through the list of items in any chapter and print out hierarchical nested UL's based on these
    two "levels": the types A and B.
