Avatar height ruler

Simple avatar height ruler, up to 4 meters in height.
To get a better indication of your avatar height

Instruction:
--------------
* Activate 'surface snap' in edit mode.
* Place the ruler on a surface that have a correct collision shape, like the default raster platform.
* Build your experience and visit it.
* Place your avatar in front of the ruler to get a indication of the height.

I tried to make this ruler correct in the height. but there's still a tolerance in height. depends on view angle and distance of the avatar from the board etc.

white lines = 10cm
blue lines = 50cm
red lines are 1 meter
