Motivation

Noticed some issues in the how modular and portable the code is.
Yes, it works fine - but it can always be more optimized for performance & it needs to actually run on computers that don't have dev tools installed. Also renaming the project to spectrum to fit the math better.

ToDo

• Remove duplicate #includes
• Rename to spectrum, reflect changes in release
• Make code portable to other systems with static linking
• Bundle the fftw3 dll with the exe for the release zip
• Add colours (courtesy of johnmilson125-png/Joe.r) Improve color rendering in visualizer #17

After posting the project to some cpp communities, I realized that I completely disregarded compiler agnosticism

• Make the program compiler agnostic
• Add 'contributing' guidelines
