= Yugine Engine
The yugine essentially is made of a sequence of levels. Levels can be
nested, they can be streamed in, or loaded one at a time. Levels are
made of levels.
Different "modes" of using the engine has unique sequences of level
loading orders. Each level has an associated script file. Level
loading functions call the script file, as well as the level file. The
level file can be considered to be a container of objects that the
associated script file can access.

.Level model
The game world is made up of objects. Levels are collections of
objects. The topmost level is called "World". Objects are spawned into
a specific level. If none are explicitly given, objects are spawned
into World. Objects in turn are made up of components - sprites,
colliders, and so on. Accessing an object might go like this:
World.level1.enemy1.sprite.path = "brick.png";
To set the image of enemy1 in level 1's sprite.
.Textures & images
A sprite is a display of a specific texture in the game world. The
underlying texture has values associated with it, like how it should
be rendered: is it a sprite, is it a texture, does it have mipmaps,
etc. Textures are all file based, and are only accessed through the
explicit path to their associated image file.
