Project 3 (thamarauder)

Uploading Lab 3 for class.

New Features:
- Pressing "A" will animate the cube, and pressing "N" will stop said animation.
- Right-clicking on the mouse will animate the sphere above the cube. Right-clicking again will stop its animation.
- A "main menu" was added with an interactive "play" button. This button will send the user to the game.

Previous features:
- Four sliders that change the color and rotation speed of the cube.
- A built-in clock.
- A coordinate-finder that shows up on the UI.
- The cube will turn invisible if the space bar is pressed - highly recommended to do after trying everything else.
- Left-click creates mini-primitive prefabs (spheres).
