  This file is the main file for the Project Euler #207 project.  It uses
  the RatioKCalculator found in ratio_k_calculator.hpp and implemented in
  ratio_k_calculator.cpp.  The program takes in FROM THE STANDARD INPUT
  (i.e. NOT from an argument file, due to the specifications in the problem)
  a number on a line corresponding to a list of queries, followed by that
  number of queries on each line.  Each query has two integers a and b.
  For details, see the readme or the problem page at:

  /*Since the problem doesn't test for checking input formatting and is really
    clear about it, I don't do any checking for proper formatting.  Don't run
    the program on one that is not properly formatted, lest it run until
    manually terminated.  I may add checks later. */
