Generate a julias set fractal curve

optional arguments:
-h, --help            show this help message and exit
-k [K [K ...]]        complex number used to create Julia set. Two numbers
                        have to be given for animation. Default is
                        0.285+0.01j. (default: [(0.285+0.01j)])
-s SIZE, --size SIZE  size of the generated image. (default: 401)
-x X                  domain size of the fractal. Default is 2.0, meaning a
                        -2 x +2, -2 x +2 square will be created. (default:
                        2.0)
-c COLORMAP, --colormap COLORMAP
                        name of the matplotlib colormap to use. (default:
                        autumn)
--pattern PATTERN     pattern use to control output. A letter corresponds to
                        a picture, several letters can be given. Description
                        is given below. (default: abcde)
-o OUTPUT, --output OUTPUT
                        name of the generated file. If not provided, result
                        will display on screen. (default: None)
-n NUMBER, --number NUMBER
                        number of pictures to generate between two complex
                        numbers. Default is 2. (default: 2)
-p, --parallel        boolean used to create images in a parallel way. It
                        used the (n-1) cores. Default is False. (default:
                        False)
