Counter Example

In this example a flow to count to a specific number.

npm run counter-example {howHigh=10000}

This counter flow makes use of halt and matchUntilHalt. This example has four rules.

1. Bootstrap - This looks for a Number fact and a non existent Counter. Once this rule is fired a counter is asserted into the session.
2. Done Counting - This rule looks for a Number and a counter that has a count equal to the Number. This rule is interesting because it calls halt() once it is fired which causes matchUntilHalt to resolve.
3. Log Count - This rule looks for a counter and logs a message every time the counter is divisible by 1000.
4. Increment Counter - This rule increments the counter.
