Remove logartifact calls from tutorial and examples

Removes calls to the non-existent logartifact function that was causing
UndefVarError. The function is not implemented in the current codebase.

Changes:
- Commented out logartifact calls with TODO reference to issue #61
- Commented out rm(plotfilename) to keep plot files available
- Added clear comments explaining the temporary workaround

This makes the tutorial functional while preserving the intent for
future implementation when artifact upload functionality is added.

Fixes #61 (temporary workaround until function is implemented)
