/**
 * Line Item Model. Mostly used for storing a snapshot of all the items in a transaction
 * as they were recorded at the time of being added to the cart.
 * There are different 'types' of line items: item, sub-item, tax, sub-total, and total.
 * Note that line items can be nested. For example, a total line item should have one-or-more
 * children sub-totals. Likewise, sub-totals should have one-or-more nested items or taxes
 * (or maybe promotions or products?). Also, items can have nested sub-items (eg. an item could be a
 * ticket, which has many sub-item prices which together make up the price of that ticket).
 * Note that line items should point to real model objects using OBJ_ID and OBJ_type (note:
 * there is a current limitation that they can only point to models with INT primary keys),
 * but this is NOT required. And in fact, the items they are related to CAN be deleted, but
 * the line item should still exist (in this case it merely shows that there was ONCE a model
 * object the line item was based off of).
 * In usage, Line Items are first stored on the EE_Cart, but not saved until a user's registration is
 * finalized (like how the EE_Transaction is stored in the session until it is confirmed).
 * Many of their methods (like
