Update Related Items.

The first thing I should say is that we need to avoid using related items groups b/c there is no base of group items that belongs to all products, simply individual items related to master items. Defining a related items group for each product on our site seems unrealistic and contrary to it's reasoning of repeatedly used sets, which we don't need.

My goal is to have a master xls file that I can use to maintain all of my product items information, and especially have 10+ columns for related items and simply ad the related item internal-id in the appropriate columns, and import to NetSuite. The goal is that NS will add/edit/delete any related product connections to products who's related products have changed, multiplied, or removed.
