/// UniqueConstraint can be used to specify that a property or list of properties taken together 
/// have unique values for all objects of that class in a datastore. A unique constraint that is based on a list 
/// of two or more properties is called a composite unique constraint.
/// This constraint type applies to all data property types except for Boolean, BLOB, and CLOB. A Boolean property 
/// can be included if it’s part of a composite unique constraint.
