Snake DLL Test

As part of an in class assignment to test our knowledge on importing a DLL and using their functions. The C++ library was written by our professor and given to us to implement in a new Unity project. Additional functionality was written in both the C++ library and in C# script. The goal was to hook up the DLL in order to use stored functions to help create a Snake game. 

Snake Game
- Player starts in bottom left, waiting for movement input from the player. Once moving, the player can change the snake's movement direction by using the WASD keys or Arrow keys. 
- When the snake collects an apple, the snake's body will grow and it's movement speed increases. 
- When the snake collides with the game border, it will come through the opposite border. 
- When the snake hits it's max body size of 10, apples will stop spawning.  The player wins!
- The player can use Spacebar to reset the game and continue playing,
- If the snake crashes into it's body, it's movement freezes and the game is over!
