-// A CHSet is implemented as an array (tab) of buckets, each of which
-// contains a pointer to a list of <T>CHNodes. Each node contains a
-// pointer to the next node in the list, and a pointer to the <T>.
-// The end of the list is marked by a next node pointer which is odd
-// when considered as an integer (least significant bit = 1). The
-// assumption is that CHNodes will all begin on even addresses. If
-// the odd pointer is right-shifted by one bit, it becomes the index
-// within the tab array of the next bucket (that is, bucket i has
-// next bucket pointer 2*(i+1)+1).
-
-// The bucket pointers are initialized by the constructor and
-// used to support the next(Pix&) method.
-
-// This implementation is not portable to machines with different
-// pointer and integer sizes, or on which CHNodes might be aligned on
-// odd byte boundaries, but allows the same pointer to be used for
-// chaining within a bucket and to the next bucket.
