Adds or replaces the items in a cart.

Field Notes
action Tells the endpoint how to treat the items being passed:
append takes all passed in SKUs and adds them to the the item list (increasing the quantity of any items already in the cart)
adjust takes all passed in SKUs and sets thier quantities to the passed in value, any other item in the cart is untouched.
replace replaces the tiems in acart with the items passed in.
remove removes the items passed in, any other item in the cart is untouched.
Type: String (append|adjust|replace|remove)
items A JSON encoded array with the following structure: 
{
    "SKU": "[Product SKU]",
    "Quantity": [Quantity of this item],
    "Autoship":[bool]
}
Type: JSON array (optional)
kit The SKU of a Promoter Kit
Type: String (optional)
pack A JSON encoded object with the following structure: 
{
    "Guid": "[Pack GUID]",
    "Quantity": [Quantity of this configuration],
    "Autoship":[bool]
    "Berry": [Quantity of Vanilla],
    "Chocolate": [Quantity of Chocolate],
    "Vanilla": [Quantity of Berry],
}
This will take the quantites of each flavor, find the SKU that matches, and add the Quantity of this SKU to your Cart. This is a convenience method to make implementing a UI easier. It only works with Packs that have a Selector of FLAVOR_QUANTITIES_MAX_2 or FLAVOR_QUANTITIES_MAX_4.
Type: JSON Object (only evaluated if you do not pass an items field) (Optional)

If sucessfull you will see a response like this:

    "error": null
}
