ResolveResult class

Result of resolving a type. This can either have the resolved type set, or it can inform the called that it needsContext to resolve the type properly. Failure to resolve the type will have the unknown flag set.

When you see a ResolveResult that is unknown or needs context in the final AST returned by SqlEngine.analyze, assume that the type cannot be determined.
