How to use
A note on Timers:

Standard Timer - specify an interval to run the library update process. It will be launched every X hours within the interval unless on of the conditions specified by you as been met (don't run during media playback, etc) in which case it will be run at the next earliest convenience.

Advanced Timer - specify a cron expression to use as an interval for the update process. By default the expression will run at the top of every hour. More advanced expressions can be configured such as:

.--- minute (0 - 59) |  . hour (0 - 23) |  |   .- day of month (1 - 31) |  |   |   .-- month (1 - 12) or Jan, Feb ... Dec |  |   |   |  . day of week (0 - 6) or Sun(0 or 7), Mon(1) ... Sat(6) V  V   V   V  V    *   *   *   *  *

Example: 0 */5 ** 1-5 - runs update every five hours Monday - Friday 0,15,30,45 0,15-18 * * * - runs update every quarter hour during midnight hour and 3pm-6pm
