increase the population size to 100

Create a new crossover algorithm

add a function to plot the average score

See merge request ii/collabschool22/genetic-bike-a!15

clean up the code
add docstring to the one_coordinate(start_point, side_length) and two_coordinates_are_the_same(coordinates)
fixed the bug: ensure that the number of the generated children is the same as the initial population
change the termination condition of the genetic algorithm: terminate when the average fitness score converge

add a auto-documentation

See merge request ii/collabschool22/genetic-bike-a!14

Image saver works

See merge request ii/collabschool22/genetic-bike-a!13

fix the bugs for imput files

See merge request ii/collabschool22/genetic-bike-a!12

Created get_img function to save bike images

See merge request ii/collabschool22/genetic-bike-a!10

two_coordinates_are_the_same

See merge request ii/collabschool22/genetic-bike-a!9

make a function two_coordinates_are_the_same(coordinates) to check if there are two identical coordinates for a bike.
change the use of random function from randint to uniform in the mutate function

This is for combined simulation with genetic function and bike function

See merge request ii/collabschool22/genetic-bike-a!8

add a simu_bike for solve the physics only, nor rendering.

Changing coordinate from tuple to list

Added .gitignore file
