For example, to create a "unique" view of a range, you use
a binary predicate

   biPred(x,y) equal to x != y.

I started out with wanting to immitate std::unique() lazily,
and then generalized it to adjacent_filered(). Bascially,
if you want to filter a range on an single objecte basis, then
why not on basis of adjacent objects?
