Feature/vision
Adds: 1: Package for using Microsoft Custom Vision and Computer Vision in Unity. 2: A Standalone Demo that shows how to use this package, called "Vision Treasure Hunt".
The assets used for this package are under /Assets/MixedRealityAzure/Vision/, and include 3 scripts and 1 prefab. No additional .dlls are needed at this point.
There is a .bat file for packaging in the future included, and the 1.0.0 version of the Unity Package is in /MixedReality-Azure-Unity/UnityPackages.
To use in a project, just import the UnityPackage, and put the VisionObject prefab in the scene, fill in options in the inspector, and send images to it. There are more instructions in the README in /MixedRealityAzure/Vision/, and an example of using it in the standalone sample.
The package has been tested in a project that also uses the LUIS package, and seems to have no conflicts.
