Error Resolver

The error resolver process is triggered when an erroneous Imports::Line is updated with a group of resolved_attributes.

The resolved_attributes contain values which should have been computed by the parser, but the parser was unable to compute these values and produced an Imports::Error instead.

The interface will allow the user to resolve one or multiple attributes related to a common Imports::Line, the Error Resolver will treat those resolved_attributes separately.
