- inherit explicit requirements that the user defined himself - but _not_ implicit requirements that cdist added for autorequire Changes: - added new .autorequire property to CdistObject to keep track of implicit autorequire dependencies - Emulator appends implicit requirements to this .autorequire property - DependencyResolver preprocess these .autorequire properties before resolving normal dependencies - refactored and documented DependencyResolver so it's clearer what happens and easier to use from tests - update test cases to match new DependencyResolver behaviour Signed-off-by: Steven Armstrong <steven@icarus.ethz.ch>
