Also user can manually define the min, max, quantity, saftey stock if required.

8- the classification of the demand is added as an output. 9- average flow time is added which is how much time on average a unit stays in stock. 10- initial inventory level can be set manually. 11- also because many have asked the ABC thresholds can be changed and up to two attributes can be added in the function abc_dynamic(). 12- negative binomial and gamme distributions are added 13- comparing distributions of demand.
