Query a SetColumn
<p>how can I search NOT CONTAINS in a set ?
Say I have the following model:</p>

<pre><code>case class ClassRoom(id:String, age:Int, name:String , kids: Set[String])
abstract class PersonModel extends CassandraTable[PersonModel, Person] {
  override def tableName = "ClassRooms"
  object id extends StringColumn(this) with PartitionKey[String]
  object age extends DoubleColumn(this) with PrimaryKey[Double]
  object kids extends SetColumn[String](this)
</code></pre>

<p>I want to do the following query</p>

<pre><code>def findMissing(minAge:Double, kid:String) = select 
.where(_.age &gt; age)
.and (_.kids not contain kid)
.fetch()
</code></pre>
