796da46ae8 Ensure that scopes are cleaned up correctly upon error. (#20) 
When evaluating rules, upon error the last pushed scope wasn't being
popped from the stack of scopes. This causes incorrect behavior
when there are multiple definitions for the same rule name.

The fix is to make sure that the scopes are popped manually upon encountering errors.

Once the interpreter logic is locked down, then we need to clean up scope management
using Drop functions so that the cleanup happens even during short circuited return.

Rename compare.rs to comparison.rs to match OPA documentation of builtins.

Also update loop handling to ensure that the current scope is restored after
each iteration of the loop so as to undo side effects of the iteration.
