The dependency relationships are stored in an ``adjacency_list`` that maps distributions to a list of ``(other, label)`` tuples where ``other`` is a distribution and the edge is labeled with ``label`` (i.e. the version specifier, if such was provided). Also, for more efficient traversal, for every distribution ``x``, a list of predecessors is kept in ``reverse_list[x]``. An edge from distribution ``a`` to distribution ``b`` means that ``a`` depends on ``b``.
