To aid with future geometry debugging, finding regressions in geometry processing and more easily allow opensource contributions, we need to construct a regression testing framework for conway/conway geometry.

Just to further clarify the implementation plan, the basic set of tasks are:

• 1. Create a state object for handling regression
• 2. Refactor the memoisation code for meshes and curves to expose more functionality at an API level.
• 3. Wire up obj dumping at a higher level inside the API for building the regression dumps.
• 4. Add memoisation of Boolean operations.
• 5. Add commenting to OBJs related to the Boolean operators.
• 6. Files in "full dump" mode will go into a directory with their expressID in the file name.
  • 6.1 Probably use a radix dir structure, like dirs for 0/, 1/, 2, ... 00/, 01/, 02/, etc. to make easier to navigate
• 7. Add SHA1 hashing for binary memoised objects.
• 8. Add a CSV manifest output with SHA1 hashes and a stable ordering.
• 9. Finalise the command line tool to support both options
