# guard 

Trivial guard: triggers callback when internal counter reaches 0.

## API

Create ```guard``` passing callback function. Call ```on()``` and ```off()``` to increase and

decrease internal counter.

    g = guard(function() {

      console.log('Done...')

    });

    g.on();

    g.on();

    g.off();

    g.off(); // prints 'Done...'

You can initialize the counter when creating a new guard.

    g = guard(function() {

      console.log('Done...')

    }, 2);

    g.on();

    // call off 3 times

    g.off();

    g.off();

    g.off(); // prints 'Done...'

In addition to `done` callback you can setup callbacks when counter reaches a certain value during

`on` or `off`

    g = guard()

      .onCallback(100, function() {

        // called when internal counter is 100 after increment

      })

      .offCallback(10, function() {

        // called when internal counter is 10 after decrement

      });
