What policy is used to generate the data?

[akiross]

Hello,
I'm just wondering, since I couldn't find it in the documentation, what is the policy used to generate the data.

For example: I guess (from the example in the README) that random values are used, but this hypothesis raises a few questions.

1. is there a fixed seed? are the values stable across multiple runs?
2. is there a guarantee that values are unique? are there any checks on this?

If data are not random, what kind of assumptions are made?

Sorry if these questions have been asked somewhere and I missed the answers, but I thing a little section on this might be useful in the how bakery behaves chapter: while there are some info there that are useful when some constraints on the data are needed, I think it's worthy to know better about the default behavior.

Also, model_bakery is very handy and I'm loving it :) Thanks for your hard work!
