// 1. Construct LeDevice with address of all 0s
// 2. IF NO IRK AND NO PRIVATE ADDRESS: (i.e. nothing in disk cache)
// a. Hopefully pairing will happen
// b. Pending successful pairing get the IRK and Private Address
// c. Set Both to device.
// (d). If available set IRK to the controller (later iteration)
// [#3 should indicate we have a bug]
// 3. IF YES IRK AND NO PRIVATE ADDRESS: (Partial Disk Cache Information)
// a. Set IRK
// b. Generate Private Address
// c. Set Private Address to device
// (d). If available set IRK to the controller (later iteration)
// 4. IF YES IRK AND YES PRIVATE ADDRESS: (i.e. Disk cache hit)
// a. Construct with private address
// b. Set IRK
// (c). If available set IRK to the controller (later iteration)
// 5. IF NO IRK AND YES PRIVATE ADDRESS (we have a bug)
// a1. -Construct with private address-
// b. -Indicate we need to repair or query for IRK?-
//
// or
//
// a2. Don't use class
