PHP Fractals Generator: Mandelbrot, burning ship and Julia sets

This class can generate Mandelbrot, Julia and burning ship set fractal images.

It can iterate a given number of times the fractal generation algorithm to render an image with the fractal image.

The generated fractal image is returned as a string with the image data in the PNG format.

The fractal type can be of Mandelbrot, burning ship or Julia set. The fractal image length and the number of algorithm iterations are configurable parameters.
