How to use the decreasing tuple idiom.

example_decreasing_tuple.cpp

#include<tector.hpp>

#include<iostream>

int main()
{
  tector<int, int, int, int> t{3, 5, 4, 1};
  t.remove_first(); // so now we just have the elements 5, 4, 1
  // Now we can call remove_first again like this:
  t.remove_first(); // Now we have the elements 4, 1
  
  std::cout << t.get<0>(); // output: 4
  std::cout << t.get<1>(); // output: 1
}
