• What does this implementation fix? Explain your changes.

• This PR works toward closing issue Reformat code to meet style guidlines #89

• Include any related logs, error, output file etc.

• N/A

• Did you test on Mac and Windows?

• I tested on Windows, but don't have access to a Mac device.

• Did you test the full GM process and verify that the code does not contribute any unexpected errors/bugs?
  *Yes.

• Did you follow the style guidelines and verify that the code does not have any incorrect formatting?

• Yes.

• If possible, provide a screenshot of the functionality.

• N/A since no functionality was changed.

• Any other information?

• I didn't add a function header comment to reloadSandwich() due to the "TODO" comment above it stating the desire to refactor it. There were some comments above that one stating confusion about when the function is called, so all of this combined is why this is the only function without a header comment.
