/**
 * This sample uses profile friends as sample connections.
 * 
 * @section usage $_GET params:
 * 
 * Display connections:
 * - id: profile ID to display connectiond for
 * - method = array: display connections using array method, just plain list of connections IDs
 * - method = sql: display connections using SQL method, custom SQL query where connection data is inserted as part of SQL query
 * - method = search-results: display connections using SearchResults class, SearchResults class must support connections
 *
 * Generate connections:
 * - action = gen: to generate sample connections for all profiles, by default around ~2 friends for each profile, and around ~1 friend request
