Homework 5: Managing the "Direct Feature" Project
===================================================

For the remaining homeworks/project you may work in groups of two and practice pair programming.

You are in charge of maintaining a software project called the DJ Library
and an influential user has just supplied a very simple feature request:

Instead of just writing strategies in the form:

{ A -> B
  B -> C
  C -> D
}

the user would like to add direct edges to the strategy graph:

{ A -> B
  direct B -> C
  C -> D
}

This means that the traversal should go from A to B and then directly through one has-a edge to B
and then to C.

The user has provided a test program in /os-should. The current DJ Library does not work
for this example while it works for /os.
Modify DJ so that it works for /os-should.

The only difference between /os and /os-should is that file os.beh has changed::

   ("{ source: Commands -> target: FileName }",cgCommandsWithoutTail));

has changed to

   ("{ source: Commands -> CreateEmptyFile direct CreateEmptyFile -> target: FileName }",
     cgCommandsWithoutTail));

What to turn in:

1.
How complex is it to add the "Direct Feature"?
Write an initial analysis before changing the code.

2.
The modified DJ library.
