Notes: (I didn't get to all of this yet)
	"virtual public" and two copies from the base class
		Why doesn't the compiler just figure this out?  
	OpenGL Debugging Messages
	Makefile revision so we don't have to always build everything
	Files:
		baseclass.cpp:  Implementations for loaded_object, and block_object, simple_cube (we don't have this yet)
		Classes are defined in game.h
		blocks.cpp and blocks.h:  Blockish wall things
		projectiles.h and projectiles.cpp:  ice balls, but we might want more
	Git:
		Hosted on isoptera
		You all have write access, so be careful
	Visual Studio:
		Did I get to this?
		I'd like the repo to build all the time, even if it makes checkouts huge
	
A small addition:
	simple_cube and texturing it

A note about walls:			
	Except for Minecraft, they're not usually a stack of cubes
	You can set a texture to repeat, and there are lots of other options too
	I'll skip Google this time:
	https://registry.khronos.org/OpenGL-Refpages/gl4/html/glTexParameter.xhtml

Texturing, round 2:
	Let's make two sanely-textured cubes!
		Version 1:  Same picture on all 6 sides
		Version 2:  Stack of pictures
		We'll skip loading from .obj for both of these.  Why?
			To show how texture coordinates work, basically
			But also:  .obj isn't really needed if we just have a cube anyway
			These will be intended to be used as base classes
	Non-cubic scaling:
		Let's add it!
		We'll set GL_REPEAT for the texture, and scale texture coordinates too
	
Alright, let's test the it by adding something fun!
	Turrets
