I'm going to use this diagram generated by g**gle g*m*ni on the school's license in my future talks on AI in education and general.

Perhaps I'm just prompting it wrong. I should have EXPLICITLY told it to not include the "matiPtuintoGrout" function. My bad. ;P

@Moosader It's using the synchronous message arrow for all relations.

Then again, as this is "facebook style codebase", maybe all the oddities are actually an accurate representation of the code. :)
