Detailed Description

Class representing one possible solution to a problem found during resolving.

All problems should have at least 2-3 (mutually exclusive) solutions:

Undo: Do not perform the offending transaction (do not install the package that had unsatisfied requirements, do not remove the package that would break other packages' requirements)
Remove referrers: Remove all packages that would break because they depend on the package that is requested to be removed
Ignore: Inject artificial "provides" for a missing requirement (pretend that requirement is satisfied)
