Dynamic module loading - you can now delete any file in the worldedit mod except init.lua, and the relevant functionality will simply not be included.

 =============
 The WorldEdit API is composed of multiple modules, each of which is independent and can be used without the other. Each module is contained within a single file.
 
+If needed, individual modules such as visualization.lua can be removed without affecting the rest of the program. The only file that cannot be removed is init.lua, which is necessary for the mod to run.

 For more information, see the [README](README.md).
