Groups are internal "grouping" of items that can be of the same type, tag, process, etc. The point of them is that you
can keep track of all of one thing in a list for quick reference. There is three pieces of key information needed in order to
create a group; a name, a type, and a basic description.
There are two types of groups you can create:
Plain - This group has no other extra features beyond being a place to keep a bunch of items categorized.
Calculated - This group will act a a substitutive group. The QOH of each item will be calculated together for you and when added to a
recipe the group will act as if the items can be used in place of each other.
