made the home page a jsp instead of an html, added rectangle pic, added image folder and images, rectangle, circle, triangle
added Enum class for shapes w/rectangle, created if statement for picking rectangle class, next will be converting the RectangleCalculations class into a service for all calculations. once I get the rectangle to work, i'll add the rest. So far the program works when running it from the home2.jsp page, will not work when running it from the Assignment 02 project.
removed rectanglecalculations page and replaced it with a calculation service page to control all calculations.
added math for rectangle from controller to calculator service
changed results page into EL results page
rectangle outputs correctly, going to add circle and triangle now
going to add redirect to index for output
