  4. ** Function:  Calculate_Simple_Interest
  5. **
  6. ** Description:  Simple Interest is the amount of interest
  7. **               calculated by using the formula:
  8. **
  9. **               interest = (P * R * T)
  10. **
  11. **               where P is the principle, r is the rate, and t
  12. **               is the time of the investment
  13. **
  14. **               This function will return the simple interest
  15. **               calculated based upon it being passed the principle,
  16. **               rate, and time.
  17. **
  18. ** Parameters:   Principle - The original principal to start with
  19. **               Rate      - The rate of interest.  If you wanted
  20. **                           9.5 percent it would be passed as 0.095
  21. **               Time      - The time in years
  22. **
  23. ** Returns:      Interest  - The amount of simple interest earned
  24. **
