   I know it's not the cleaner way,  but in C (not in C++) to get
   performances and genericity...
 
-  Some example of insert and search follows here. The search is a plain
-  normal search over an ordered tree. The insert instead must be implemented
-  in two steps: First, the code must insert the element in order as a red leaf
-  in the tree, and then the support library function rb_insert_color() must
-  be called. Such function will do the not trivial work to rebalance the
-  rbtree, if necessary.
