/* CSCI 261 Lab03B: Triangles Classifier + Options Menu
*
* Author: _INSERT_YOUR_NAME_HERE_
*
* The goal of this lab is to practice the use of if-else statements to classify triangles based on their sides.
* It will also teach you how to correctly compare double values for equality using a tolerance factor and
* the use of a menu of options using the switch statement.
