CPPND: Capstone Snake Game Example

This is a starter repo for the Capstone project in the Udacity C++ Nanodegree Program. The code for this repo was inspired by this excellent StackOverflow post and set of responses.

The Capstone Project gives you a chance to integrate what you've learned throughout this program. This project will become an important part of your portfolio to share with current and future colleagues and employers.

In this project, you can build your own C++ application or extend this Snake game, following the principles you have learned throughout this Nanodegree Program. This project will demonstrate that you can independently create applications using a wide range of C++ features.

Rubrics

Loops, Functions, I/O

Add command line arguments to set speed, screen width, screen height
```
./SnakeGame -h
```

OOP

Define new private members like mutex references(valid for Memory management), game state and speed
Use lambda functions with thread
Overload Renderer::UpdateWindowTitle for strings

Memory Management

Store Renderer as shared_ptr and share between Controller and Game logic
- Controller will update title on game pause

Concurrency

Add controller thread that handles keyboard events
- Use 'SPACE' key to stop, resume game
Use mutex between controller and game_run loop
