For example: (all variables are int type)
a-c+d is expressed as tree (a-c)+d, but I hope IBURG can transform it
to (a+d)-c.
Another example is: a+b+c+d is originally expressed as tree
((a+b)+c)+d, can I write IBURG rules to change the tree to
(a+b)+(c+d).


Does it possible for IBURG rules to do the above job? Or it is just
above the ability of IBURG?
