-- | Given a dependency graph, buildResultGraph detects and propagates errors in that graph as follows:
-- 1. Mark each node that is part of an import cycle as an error node.
-- 2. Mark each node that has a parse error as an error node.
-- 3. Mark each node whose immediate children could not be located as an error.
-- 4. Recursively propagate errors to parents if they are not already error nodes.
