Detailed Description

template<typename DERIVED, typename IT, typename S_FN>
class adobe::step_iterator_adaptor< DERIVED, IT, S_FN >

An adaptor over an existing iterator that changes the step unit (i.e. distance(it,it+1)) by a given predicate. Instead of calling base's operators ++, --, +=, -=, etc. the adaptor is using the passed policy object S_FN for advancing and for computing the distance between iterators.
