--[[  scenriLua - In world objects as skang Things.

TODO - Yes I know this breaks our design goals,
       but it's the easy way to quickly whip up in world object loading.
       Later a C + eet version will be written to fit our design,
       and this Lua based version will be kept.
       The system should "compile" Lua based files to eet as well.
       For now Lua based files is easier to debug.
