3 - Mesh2HRTF Complete Beginner’s tutorial v2022-06

NOTE: It is recommended to use the latest Mesh2HRTF release and follow the LATEST version of this Tutorial - This snapshot is available mostly for historic reference.

This is a snapshot tutorial that matches the fully functional but obsolete Mesh2HRTF_v2022-06 version. This version closely matches Mesh2HRTF used in the complete YouTube video tutorial course. (The videos are still relevant when combined with the updated written tutorials.)
