  @brief Multiway-branch tree manipulation

  @details This package provides two layers of functions. Functions
  of the lower level manipulate multiway-branch trees, implemented
  according to the classical scheme whereby each node points to its
  first child and its previous and next siblings. These functions are
  collected in mtrBasic.c.<p>
  Functions of the upper layer deal with group trees, that is the trees
  used by group sifting to represent the grouping of variables. These
  functions are collected in mtrGroup.c.

  @see The CUDD package documentation; specifically on group
  sifting.
