Links input

Again, this is analogous to the nodes.

{}
...
const char* LINKS_FILE_NAME = "T.links";
...

/home/nagel/src/book/sim/book/SimWorld::readLinks

Regarding addOutLink and addInLink see next section.

Task 6.3   Write code that does the links input.

Remember that you need to include Links into the SimWorld class similarly to Nodes.
