YAML object now can handle complex array.

Signed-off-by: Toha <tohenk@yahoo.com>
Enable composite foreign keys.

The current foreign keys ignore composite foreign keys. ForeignKey object now
provide getLocals() and getForeigns() method which returns array of Column
object. The method getLocal() and getForeign() then should be removed in
near future.

This change may break compatibility with existing formatter. Also, this change
may be affect issue #63.
