Potential Problems:
1. Facebook api rate limits, it looks reasonably high though?
2. LinkedIn appears to be easy, but I’ve never seen an app use it, something fishy is up, SO comments saying 100x100 is best available

App Parts:
1. Authorization Screen - auth with all networks and iOS contacts
2. Processing Screen - show progress
3. Results Screen - show contact name, then every avatar below in a row, allow tap selection of any 1 avatar per row
4. Apply Screen - applies selected photos to contacts and show progress
