 * Attributes are a name-value pairs. The name is the type of the attribute, as

 * are specified by the ATTRIBUTE_TYPE enumeration. Custom attribute types may
 * be created by constructing a BlackboardAttribute.Type object and calling the
 * SleuthkitCase.addArtifactAttributeType method. The BlackboardAttribute.Type
