69  Synopsis    [Structure representing multi-level logic by quotient, divisor,
70  and remainder.]
71
72  Description [Structure representing multi-level logic by quotient,
73  divisor, and remainder. In spite of the name this is a graph
74  structure, not a tree.  Each node of the graph has 3 children:
75  quotient, divisor, and remainder. The purpose of the field
76  complement is to have both phases in a tree, so if the field 'comp'
77  is set to 1, then the field 'complement' is taken instead of the
78  field 'node'. When an output function is the same as either another
79  output function or the complement of another function, the tree of
80  the output function is made by copying the tree of the other
81  function, then the field 'ref' of this tree is set to 1. The fields
82  'q(d,r)_ref' tell each child tree was newly created or already
83  existing, and the fields 'q(d,r)_comp' tell whether each child tree
84  is complemented or not.  To increase sharing, every time a function
85  is factored, a tree representing quotient * divisor is made if the
86  tree does not exist, and the field 'candidate' of this tree is set
87  to 1.]
