Auto-generate database migrations

[CatarinaPBressan]

I'm coming from a python background, and there I used sqlalchemy ORM with the alembic migration tool.

What I liked about Sugar was how nice it is to write queries and set up models. It reminds me of SQLAlchemy, and that is a very good thing.

However, while you guys do provide migrations via the sql files in the migrations folders, I feel that since it doesn't auto-generate migrations, the usability of Sugar is dimished somewhat, especially sice we are talking about SQLite, which is full of little details that make writing certain migrations (ALTER TABLEs come to mind) a pain.

I also want to say that I am aware that this is a really tall order. Alembic is a huge project, is probably just as complex, and at the end of the day I still have to validate the scripts that it generates. Even so, I feel that it is important to Sugar to consider having this kind of tool.

Thanks!
