Reinforcement Learning training environments with ML-Agents Release 6.

1. Replace following folders and files from the new released ML-Agents Project:
   • [offical ml-agents path]/Project/Assets→[UnityEnvs path]/Assets
   • [offical ml-agents path]/Project/Packages→[UnityEnvs path]/Packages
   • [offical ml-agents path]/Project/ProjectSettings→[UnityEnvs path]/ProjectSettings
   • [offical ml-agents path]/Project/Project.sln.DotSettings→[UnityEnvs path]/Project.sln.DotSettings
   • [offical ml-agents path]/com.unity.ml-agents→[UnityEnvs path]/Packages/com.unity.ml-agents
   • [offical ml-agents path]/com.unity.ml-agents.extensions→[UnityEnvs path]/Packages/com.unity.ml-agents.extensions
2. Modify [UnityEnvs path]/Packages/manifest.json：
   • Remove the key com.unity.ml-agents or change the value of it from "file: ../../com.unity.ml-agents" to "file: ./com.unity.ml-agents"
   • Remove the key com.unity.ml-agents.extensions or change the value of it from "file: ../../com.unity.ml-agents.extensions" to "file: ./com.unity.ml-agents.extensions"

Create a unique folder in [UnityEnvs path]/Assets/Environments and then implement your own training environment following the guide in ml-agents.
