Stock Lot Shelf Life Expiration Date
####################################
The stock_lot_sled module adds two fields on lot of products:
- Shelf Live Expiration Date
- Expiration Date
And it defines on the product the default time for those fields and on the
stock configuration the Shelf Live Delay.
When the shelf life of a lot expires in less than the configured shelf life
delay, it is no more used to compute the forecast quantity of the stock.
