Entry identifier class for items of a DataSet.
Every item in a DataSet is assigned a DataKey by which it can be accessed (using DataSet::operator[]()). A DataKey consists of an integer member idx, which is a positive number for any valid DataKey. No idx of an element in a DataSet may exceed the sets max(). This property may be used to build arrays with additional information to the elements of a DataSet.
In addition, DataKeys provide a member info which can be used to store further information.
Each DataKey is unique for one DataSet but different DataSets may (and generally will) manage the same DataKeys. When an element is removed from a DataSet its DataKey may (and generally will) be reused for other elements added to the DataSet later on.
