  Title: Working with associations

  This example demonstrates the use of associations.
  First of all, Person is getting associated via many-to-many with other Person objects (e.g. Person.hasMany('brothers')).
  Afterwards a Person becomes associated with a 'father' and a mother using a one-to-one association created by hasOneAndBelongsTo.
  The last association has the type many-to-one and is defined by the function hasManyAndBelongsTo.
  The rest of the example is about setting and getting the associated data.
