template<typename IterFirst , typename IterLast >
IterFirst syten::select_cutoff_jump ( IterFirst  beg,
IterLast  end,
SRDef  threshold = 1e5 

Returns an iterator to the first element after the first relative jump greater than threshold.

If there is no relative jump greater than threshold, returns beg advanced until beg == end.

Requires [beg, end) to be sorted in descending order by absolute value. If *beg == 0., returns beg.
