  /**
   * The preferred way to define column metadata is not not define them (!)
   * Squeryl has default mappings for all Java primitive types.
   * Scala/Java
   * Int/int  -> 4 byte number
   * Long/long  -> 8 byte number
   * Float/float -> 4 byte floating point
   * String -> varchar(256)
   *
   * The default mappings can be overridden at the field/column level using the
   * Column attribute, and they can also be  overridden at the Schema level
   * by overriding the method. For example, the following causes all string
   * field in the schema to become varchars of length 64 :
   *
   * override def columnTypeFor(fieldMetaData: FieldMetaData, databaseAdapter: DatabaseAdapter) =
   *   if(fieldMetaData.isStringType)
   *     return "varchar(64)"
   *   else
   *     super.columnTypeFor(fieldMetaData, databaseAdapter)
