> We have to analyze this first to see if it is a big problem, with a huge N. I believe it is.
> Right now our search method is O( n ), while using Apple's search method it is possibly O( log n ) - but that's just a guess if I assume internally they use a binary search.
> Steps:
> 1. Grab all the contacts in a NSArray through ABAddressBookCopyArrayOfAllPeople
> 2. Construct a NSPredicate for the filter, and call filteredArrayUsingPredicate on the NSArray returned in step 1.
> 3. Convert the NSArray returned in step 2. to our CDVContact objects
