-\class QxtNullable QxtNullable
-\ingroup QxtCore
-\brief distinct null value compatible with any data type.
-
-in general it's a templated abstraction to allow any data type to be
-expressed with a null value distinct from any real value. An example
-of such a use is for optional arguments.
-\n
-prepare a function for argument skipping:
-
-\code
-void  somefunction( qxtNull(int,a) , qxtNull(int,b) )
-{
-
-if (!a.isNull())
-       {
-       int i = a.value();
-       //do something with i
-       }
- if (!b.isNull())
-       {
-       int x = b.value();
-       //do something with x
-       }
-}
-\endcode
-
-usage:
-\code
-
-somefunction(SKIP,1,2);
-somefunction(3,4);
-somefunction(3,SKIP,6);
-somefunction(1);
-\endcode
