The foreign constraint database info is read into ForeignKey. Each column is provided with its foreign key
definition.
Table exposes tables it references and other tables that reference it. Table also exposes all columns it
owns that are foreign keys.
Column exposes both the other columns it references and other columns that reference it.
ForeignTable and ForeignColumn are used to hold both sides of the relationship. They also
expose the name of the constraint and the names of the tables or columns it includes. These structs
assist in serializing the relationships without recursion.
