Unsupervised learning for AI-exhibits

This is a version of the unsupervised learning app (from within https://github.com/IMAGINARY/ai-to-touch-prototypes) adapted to the AI-exhibits project.

Changes

• Removed all dependencies to CindyJS.
• Added a Level 4 (guess where the professor is going).
• Added a URL parameter level selector (?level=4)
