calcium.arcade ?

[LeonLenclos]

Hello,

the example platform_system.py use a module called arcade. This module does not exists (platform_system.py raise an ImportError).

What about this module ? Is it a an aborted feature ? Or not yet implemented ?

By the way, for some reason i can't run pong.py and windfarm.py

Otherwise the tool looks great. Thank you for all this work !!
