Here it is.

Say you have a collection of car objects:

• Type Descriptor TypeID
  FORD ESCORT 3
  HONDA CIVIC 1
  HONDA CRX 1
  TOYOTA 4RUNNER 2
  TOYOTA CAMRY 2

Say this collection is called MySaleCollection, which contains encompasses a sale containing cars from any amount of manufacturers.

Challenge:

Write a function that would take the MySaleCollection and generate a collection of CarCollections with EACH CAR COLLECTION ONLY CONTAINING cars from the same manufacturer...


so the function returns a collection of collections... with each collection only containing that certain manufacturer's cars....

The goal is to pass an Invoice into this function, and have the function return a collection of seperate Purchase ORders.. each only containing cars from that manufacturer...
