class MigrationStep:
"""Base MigrationStep class, aka evolver.
You develop your own steps, and then pass a list of those steps to the
Migrator instance that will run them in order.
When the migrator runs, it will take the list of steps you gave him,
and, for each step:
a) instantiate it, passing the context you gave to the migrator
into the step's __init__().
b) run() the method in the migration step.
As you can see, the default MigrationStep constructor makes the passed
context available as self.context in the methods of your step.
Each step has two member vars that determine in which order they
are run, and if they need to run:
- from_level = the schema level that the database should be at,
before running the evolver
The value None has special meaning here, it
