This property should return the field name that uniquely identifies each object
within the collection. As opposed to the ordinal/index position, the key field
provides another method of accessing a particular object within the collection.
The key field must be unique within the collection. If the DatabaseObjects.Subset
function has been implemented then the key field only needs to be unique within
the specified subset, not the entire table. Implementing this function is optional.
