WIKAR v14

In preparation for new AR projects, I updated Wikar to improve performance and add features. This included implementing a multi-tiered caching system that checks for updates on the Clowder server before downloading content, enabling an offline mode for sculpture gardens with poor wifi. I also developed an iterative solver that uses a scan's confidence rating to progressively refine the AR scene's origin, maximizing placement accuracy as a user moves around a QR code. Lastly, an optimized mesh slicer system to allow users to explore 3d cross sections of complex models such as buildings.
