Submodel naming and organization

[Lasse Deleuran]

A popular convention seems to be naming the sub assemblies, such as "wing", "windscreen", etc. but this obviously becomes a challenge once sub models do not resemble anything. When that happens, I start numerating on the assembly that they are part of. As an example, windscreen.ldr might have sub assemblies windscreen1.ldr and windscreen2.ldr.
