MigrationPlan class

A roadmap of operations which cumulatively describe how a database is migrated (upgraded or downgraded) from any version to any version.

The MigrationPlan is conceptually a map associating each database version with a list of Migrations. These operations would commonly include such things as creating tables, populating initial data, and adding columns.

Constructors
