First Day in Unreal 4: 1

Learned how to open and create new projects, and the three different methods of viewport navigation.

1. left click to move forward and backward, right click to look around, and middle click to move up and down
2. alt-left click to rotate around a selected object, alt-right click to zoom in and out, and alt-middle click to pan
3. hold right click and WASD to move and Q and E to move up and down

Learned how to place and select objects, and how to switch views in the viewport
