Exercise 4.3: Using RKSUITE with specified parameters.

Repeat Exercise 4.2 using RKSUITE with TOL, THRES(1)=1, and METHOD=2. Are the actual errors within the requested tolerance? Which problems needed the most time, i.e., required the most number of function evaluations? Why? How does the amount of work compare in each case with that of using the classical Runge-Kutta formula (See Exercise 4.2)?
