Mapping requirements directly to code

It is not always desirable to go through the full process of creating a dependency graph and pseudo code for each project or change. Here, we will transition directly from the preceding plan to the following code stubs.

Writing the physics simulator

The physics simulator in src/physics.rs is responsible for modeling the physics and layout of the building and elevator operations. The simulator will be provided with one object to handle motor control and another to handle data collection. The physics simulator module will define traits for each of those interfaces, and the motor control and data collection objects should implement each trait, respectively.

Let's start by defining some...
