// A monkey has an array of items that it has created.
// It can randomly choose to add an item, delete an item, or update the data in an item.
//
// All items exist within the access group "manifeststresstest"
// which is set to have the appropriate view hint so that it syncs via CKKS.
//
// Items are generic password items, having a service, an account and data.
// The service, account and data values are chosen from sets of a limited size, to encourage
// the possibility of collisions.


// Adds and deletes generic password items
