/*  Programming Project 5 -- Functions
**  This program simulates a refinery where six separate processes are read from
**	  a data file and monitored at each time interval. This program determines
**	  how many intervals to monitor, and of the 6 pressure readings in each
**	  interval, determines the highest, lowest, and average pressures of each
**	  interval. It also prints a DANGER message for overpressures and vacuums.
