 *
 * ### Possible keys in association
 *
 * - `className`: the class name of the model being associated to the current model.
 *   If you're defining a 'Profile belongsTo User' relationship, the className key should equal 'User.'
 * - `foreignKey`: the name of the foreign key found in the current model. This is
 *   especially handy if you need to define multiple belongsTo relationships. The default
 *   value for this key is the underscored, singular name of the other model, suffixed with '_id'.
 * - `conditions`: An SQL fragment used to filter related model records. It's good
 *   practice to use model names in SQL fragments: 'User.active = 1' is always
 *   better than just 'active = 1.'
 * - `type`: the type of the join to use in the SQL query, default is LEFT which
 *   may not fit your needs in all situations, INNER may be helpful when you want
 *   everything from your main and associated models or nothing at all!(effective
 *   when used with some conditions of course). (NB: type value is in lower case - i.e. left, inner)
 * - `fields`: A list of fields to be retrieved when the associated model data is
 *   fetched. Returns all fields by default.
 * - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
 * - `counterCache`: If set to true the associated Model will automatically increase or
 *   decrease the "[singular_model_name]_count" field in the foreign table whenever you do
 *   a save() or delete(). If its a string then its the field name to use. The value in the
 *   counter field represents the number of related rows.
 * - `counterScope`: Optional conditions array to use for updating counter cache field.

 *         'className' => 'Address',
 *         'foreignKey' => 'user_id'
 *     )
 * );
 * }}}
 *
 * ### Possible keys in association
 *
 * - `className`: the class name of the model being associated to the current model.
 *   If you're defining a 'User hasOne Profile' relationship, the className key should equal 'Profile.'
 * - `foreignKey`: the name of the foreign key found in the other model. This is
 *   especially handy if you need to define multiple hasOne relationships.
 *   The default value for this key is the underscored, singular name of the
 *   current model, suffixed with '_id'. In the example above it would default to 'user_id'.
 * - `conditions`: An SQL fragment used to filter related model records. It's good
 *   practice to use model names in SQL fragments: "Profile.approved = 1" is
 *   always better than just "approved = 1."
 * - `fields`: A list of fields to be retrieved when the associated model data is
 *   fetched. Returns all fields by default.
 * - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
 * - `dependent`: When the dependent key is set to true, and the model's delete()
 *   method is called with the cascade parameter set to true, associated model
 *   records are also deleted. In this case we set it true so that deleting a
 *   User will also delete her associated Profile.

 * {{{
 * public $hasMany = array(
 *     'Comment',
 *     'Task' => array(
 *         'className' => 'Task',
 *         'foreignKey' => 'user_id'
 *     )
 * );
 * }}}
 *
 * ### Possible keys in association
 *
 * - `className`: the class name of the model being associated to the current model.
 *   If you're defining a 'User hasMany Comment' relationship, the className key should equal 'Comment.'
 * - `foreignKey`: the name of the foreign key found in the other model. This is
 *   especially handy if you need to define multiple hasMany relationships. The default
 *   value for this key is the underscored, singular name of the actual model, suffixed with '_id'.
 * - `conditions`: An SQL fragment used to filter related model records. It's good
 *   practice to use model names in SQL fragments: "Comment.status = 1" is always
 *   better than just "status = 1."
 * - `fields`: A list of fields to be retrieved when the associated model data is
 *   fetched. Returns all fields by default.
 * - `order`: An SQL fragment that defines the sorting order for the returned associated rows.
 * - `limit`: The maximum number of associated rows you want returned.
 * - `offset`: The number of associated rows to skip over (given the current
 *   conditions and order) before fetching and associating.
 * - `dependent`: When dependent is set to true, recursive model deletion is
 *   possible. In this example, Comment records will be deleted when their
 *   associated User record has been deleted.
 * - `exclusive`: When exclusive is set to true, recursive model deletion does
 *   the delete with a deleteAll() call, instead of deleting each entity separately.
 *   This greatly improves performance, but may not be ideal for all circumstances.
 * - `finderQuery`: A complete SQL query CakePHP can use to fetch associated model
 *   records. This should be used in situations that require very custom results.

 *     )
 * );
 * }}}
 *
 * ### Possible keys in association
 *
 * - `className`: the class name of the model being associated to the current model.
 *   If you're defining a 'Recipe HABTM Tag' relationship, the className key should equal 'Tag.'
 * - `joinTable`: The name of the join table used in this association (if the
 *   current table doesn't adhere to the naming convention for HABTM join tables).
 * - `with`: Defines the name of the model for the join table. By default CakePHP
 *   will auto-create a model for you. Using the example above it would be called
 *   RecipesTag. By using this key you can override this default name. The join
 *   table model can be used just like any "regular" model to access the join table directly.
 * - `foreignKey`: the name of the foreign key found in the current model.
 *   This is especially handy if you need to define multiple HABTM relationships.
 *   The default value for this key is the underscored, singular name of the
 *   current model, suffixed with '_id'.
 * - `associationForeignKey`: the name of the foreign key found in the other model.
 *   This is especially handy if you need to define multiple HABTM relationships.
 *   The default value for this key is the underscored, singular name of the other
 *   model, suffixed with '_id'.
 * - `unique`: If true (default value) cake will first delete existing relationship
 *   records in the foreign keys table before inserting new ones, when updating a
 *   record. So existing associations need to be passed again when updating.
 *   To prevent deletion of existing relationship records, set this key to a string 'keepExisting'.
 * - `conditions`: An SQL fragment used to filter related model records. It's good
 *   practice to use model names in SQL fragments: "Comment.status = 1" is always
 *   better than just "status = 1."
 * - `fields`: A list of fields to be retrieved when the associated model data is
 *   fetched. Returns all fields by default.

 * - If three fields are specified, they are used (in order) for key, value and group.
 * - Otherwise, first and second fields are used for key and value.
 *
 * Note: find(list) + database views have issues with MySQL 5.0. Try upgrading to MySQL 5.1 if you
 * have issues with database views.
 *
 * Note: find(count) has its own return values.
