 *
 * Basic logging capability provided by wrapping Apple's Unified Logging
 * Framework. Works with iOS 10 and later.
 * Log statements are written with a call the `os_log` API which takes a
 * message, an `OSLog` reference and log level.
 * Several static references to `OSLog` objects are defined, each of which
 * determines the subsystem and category of subsequent log statements.
 * Both subsystem and category are useful for filtering with the Console app.
 * Use the same subsystem name for all `OSLog` objects created here, but specify
 * a unique category to identify related functionality.
 * Add as many static `OSLog` resources as necessary to support new log
 * categories.
