Order List - Represents and Manipulates an ordered list of packages.
A list of packages can be ordered by a number of conflicting criteria
each given a specific priority. Each package also has a set of flags

- The rules listed above my never be violated and are called Critical.
+ The rules listed above may never be violated and are called Critical.
When a critical rule is violated then a loop condition is recorded
and will have to be delt with in the caller.
+
+ The ordering keeps two lists, the main list and the 'After List'. The
+ purpose of the after list is to allow packages to be delayed. This is done
+ by setting the after flag on the package. Any package which requires this
+ package to be ordered before will inherit the after flag and so on. This
+ is used for CD swap ordering where all packages on a second CD have the
+ after flag set. This forces them and all their dependents to be ordered
+ toward the end.
+
+ There are complications in this algorithm when presented with cycles.
+ For all known practical cases it works, all cases where it doesn't work
+ is fixable by tweaking the package descriptions. However, it should be
+ possible to impove this further to make some better choices when
+ presented with cycles.
