Any way to reduce quantity of a producto without removing it?

Adding negative quantity does not work

Atm you can do it like this:

update(id,'quantity', get(id).quantity - 1) 

But I agree, there should be increase / decrease methods.
I will implement them and extend the library.

@rusosnith I've added a new method called "quantity". One can use this to increase/decrease the quantity value without querying the current value of the product (like in my example above).

You can use it like this:

quantity(id,1)
quantity(id,-1)

that is awesome indeed! thanks!
