Hello, I have a requirement to create an object relationship very similar to the Organization object. However, I cannot use the Org object. 

I need to be able to represent 3 levels of business structure:  Region -> Market -> Store.

• Region contains many Markets.
• Market contains many Stores and is associated with 1 Region.
• Each store will only be associated with 1 market and region.

Use Cases (need to be able to do the following):

• Select a Store and see the Market and Region associated with that Store.
• Select a Market to see all the Stores associated with that Market
