C++ step1

The C++ enhancement in 0.2 is just for basic features. The C-source must be included too.
Now a "class LnkdLst " is available where the basic C lnkdlst features are integrated and settings could be done for a specific linked-list, like use dynamic or static Linked-List-Elements (nodes).
The one and only Test-Code based on the Linked-List tutorial from Karlina Beringer. (thanks)
