Hi Ime

You are right, basically:

a) ProgramInstance = enrollment
b) ProgramStageInstance = event

I know it can be confusing as we are exposing the internals with different
names, but its a bigger task of renaming it internally (sql tables etc)
then externally.

For sure everyone on the team know we are not the best at code
documentation, but we will try and improve.
