Create "Top Unknown Callers" page

[jMyles]

This will be a page of the most important, but still unknown callers, sorted by a combination of:

*How many times they've called
*How many recordings we have of them
*How recently they've called.
*Whether or not they're 845.

It will show these piece of information on a table, along with the phone number itself. We can then go to the phone number profile to listen to the recordings and hopefully make a positive ID and create a ContactInfo object.
