fixed name of DepthService, file and class mismatch not allowed
fixed material for depth and rotation
initial version of object that creates all joints
body service is now a regular class. joint spawner will create bodies to visualize
working on spawning stuff. also finally pushed the scene hopefully
no longer logging null depth frames
joints now drawn on depth map
using localPosition instead of weird scaling
all joints are now drawn
added body mask
added a material for mask and color per user
created prefabs for the 3 camera things
