Golang Fourier Approximation

Fourier approximation of a square wave.

This project was designed as a proof-of-concept and as a test for myself in using Go's concurrency tools. In addition, this project doesn't use any external numerical libraries, so all mathematical functions were either provided by standard Go or implemented by hand (like numerical integration).

Plotting was done via outputting the data directly to a text file and then plotting the data within through Gnuplot.
