Renamed old LinkedCell class to LinkedCell_deprecated.

  • this is preparatory for a smooth transition to the new implementation.
  • note that class LinkedCell and namespace LinkedCell bite each other so far.
  • Property mode set to 100644

4 * If the linked cell should be usable, the class has to inherit LCNodeSet and the nodes (containing the Vectors) have to inherit LCNode. This works well
5 * for molecule and atom classes.
