[VicPiMakers Projects] Make class out of functions

[Michelle Wiboltt]

“As yet undetermined” meaning for instance, once attributed say to u mark aka space boy with no “slicing” words/intents but rather leap frogging to/for back/forth , again intent wouldn’t this suggest time 🧭 travel? Does this make sense?
Further, re: attached clock with no numbers/arms thereby “opening” rather than closing time...

Unsigned / shouldn’t it read “as yet unattributed”

Quick update:

You probably want to add unsigned in front of
all the long ints, or adjust the type as needed
(all over, including  the "const" values).
