This assignment will involve implementing each feature one$-$by$-$one. Each feature involves implementing a set number of functions and classes which will be used in our program. Each feature is separate, meaning adding a new feature does not require any changes to your existing features to incorporate. In addition, when running the program, the user can specify which features they want run in their program, meaning not necessarily every feature needs to be used. As example, we could create a circuit from inputs with mirrors added into it $($Feature $1,2$ and $4),$ but not want to run it $($Feature $3).$ This creates a very flexible and modular program that is easy to extend.
