NAME
       composeBdd - substitutes an index by a BDD in another BDD

SYNOPSYS
       #include "logmmm.h"
       pNode composeBdd(pBdd1,pBdd2,index)
       pNode pBdd1;
       pNode pBdd2;
       short index;

PARAMETERS
       pBdd1               BDD in wich index is substituted

       pBdd2               BDD that replaces index

       index               index to substitute

DESCRIPTION
       composeBdd() constructs the graph for the function obtained by
       composing pBdd1 and pBdd2.  This function can be used when an auxiliary
       variable has been mistaken for a primary input.

EXAMPLE
       #include "mutnnn.h"      /* mbk utilities */
       #include "logmmm.h"
       pNode nodeA,nodeB;
       pNode res;

       initializeBdd(SMALL_BDD);
       nodeA = createNodeTermBdd(3);
       nodeB = createNodeTermBdd(3);
       res = applyBinBdd(OR,nodeA,nodeB); /* res = (OR a b) */
       res = composeBdd(res,notBdd(nodeB),2);  /* composition : a = (NOT B) */
       displayBdd(res,1);

       /* it will display
       @res   ONE
       */

       destroyBdd(1);
