Set and decrease for counter

Modify the code of makeCounter() so that the counter can also decrease and set the number:

• counter() should return the next number (as before).
• counter.set(value) should set the counter to value.
• counter.decrease() should decrease the counter by 1.

See the sandbox code for the complete usage example.

P.S. You can use either a closure or the function property to keep the current count. Or write both variants.
