///
/// The Migration theory is based on the ruby on rails concept.
/// Each database driver is going to be allowed to have files in
/// Resources that specify the database migrations. They will be
/// of the form:
///
/// 001_Users.sql
/// 002_Users.sql
/// 003_Users.sql
/// 001_Prims.sql
/// 002_Prims.sql
/// ...etc...
///
/// When a database driver starts up, it specifies a resource that
/// needs to be brought up to the current revision. For instance:
///
/// Migration um = new Migration("Users");
/// um.Upgrade(dbconnection);
///
/// This works out which version Users is at, and applies all the
/// revisions past it to it. If there is no users table, all
/// revisions are applied in order. Consider each future
/// migration to be an incremental roll forward of the tables in
/// question.
