CleanCode - VWmS ESA

The original TikTakToe from the initial commit was from a previous excercise in Data Science. I started with that version and improved the code cleanness with every commit.

The changes in each steps are rougly described below.

Step by step explanation

Step 1

• File restructuring
• Splitted game logic from user input and output [SoC]

Step 2

• improved meaning of player_one:boolean ==> current_player: number variable
• extracted switching players to own method

Step 3

• improved logic for game state variables win:boolean ==> game_over: number
• seperated "doing" from "calling" code regarding these variables

Step 4

• seperated player characters (X, O, or whatever character the user could choose from) from the actual game logic. Characters are now handeled by the UI class [SoC]

Step 5

• general refactoring
• code order now fitting better to the game logic
• added comments for better understanding of each function
