Survival Tutorial: There is a TTE when event=0

[legaultmarc]

Perhaps it is me who misunderstood, but in the tutorial on survival analysis, we can see this line:

NA06994 569.4273004275149 0 48 20.2946857226 1

Where 569.4273004275149 is the time to event and 0 means that the event was not observed.

If I understand correctly, there shouldn't be a TTE if the event was unobserved and this line would be incorrect.

Hence my proposed fix is to correct this in the tutorial and to add a check in genipe to warn the user about such ambiguities.
