A hook that lets subclasses of Global define whether a package or class should be kept loaded for the
next compiler run. If the parameter sym is a class or object, and clearOnNextRun(sym) returns true,
then the symbol is unloaded and reset to its state before the last compiler run. If the parameter sym is
a package, and clearOnNextRun(sym) returns true, the package is recursively searched for
classes to drop.
Example: Let's say I want a compiler that drops all classes corresponding to the current project
between runs. Then keepForNextRun of a toplevel class or object should return true if the
class or object does not form part of the current project, false otherwise. For a package,
clearOnNextRun should return true if no class in that package forms part of the current project,
false otherwise.
