working on project structure

I’ve been working on better project structure. I added some classes, that make the rendering easier:

• HarmonicShape
  • the shape, encoded in harmonics
• RenderStyle
  • stores the color, width and in the future other render propereties.
• StyledShape
  • the final shape object, that combines the harmonic shape and the render style.
  • will store the animation for the shape (modifies harmonics)
• HarmonicSprite
  • stores a list of shapes (StyledShape) and handles updates and animations
• PygameRenderer
  • renders sprites on the screen

Also I added a fft function to later transform points into harmonics. - next i will make a drawing tool, and make an alphabet.
