4 * Class History
5 *
6 * Handle the history file tracing events in Shaarli.
7 * The history is stored as JSON in a file set by 'resource.history' setting.
8 *
9 * Available data:
10 * - event: event key
11 * - datetime: event date, in ISO8601 format.
12 * - id: event item identifier (currently only link IDs).
13 *
14 * Available event keys:
15 * - CREATED: new link
16 * - UPDATED: link updated
17 * - DELETED: link deleted
18 * - SETTINGS: the settings have been updated through the UI.
19 *
20 * Note: new events are put at the beginning of the file and history array.
