SDL2 Hello World

sdl2HelloWorld.py

"""Simple example for using sdl2 directly.
Event prints out on the terminal
event.type      - type of event
event.key...    - symbolic key code for checking which key is checked
event.mouse.x/y - x and y position of the mouse within the window.

Used help from PySDL2 readthedocs page.

Window background code is commented out as it requires a BMP file. Just rename actual file/filename in the code and comment out.
