Improve error messages displayed when assert/retracting non-dynamic predicates #206

Closed s-webber closed 2 years ago

s-webber commented 2 years ago

Improve the error messages that are displayed when the assert and retract built-in predicates fail due to the given predicate not being dynamic (i.e. it is a static user defined predicate or a built-in predicate.)
