10	* Class Log
11	*
12	* The static facade intended to be the primary way of logging within GiveWP to make life easier.
13	*
14	* @since 2.21.0 Use array_diff_key to filter context data to prevent php warning with multi-dimension array
15	* @since 2.20.0 add sensitive information redaction; store context as arrays for JSON serialization
16	* @since 2.19.6 added debug
17	* @since 2.10.0
18	*
19	* @note There are two special keywords used in the context that are representing category and source.
20	* The default value for the Category is "Core" and for the source is "Give Core"
21	* If you want to change the category and/or source, you should provide them as context attributes.
22	* Source and category attributes should be written lowercase.
23	*
24	* @example
25	*
26	* Log::error( 'Error message', [
27	* 'category' => 'Payment',
28	* 'source' => 'Stripe add-on'
29	* ] );
30	*
31	* @note Use as many contexts attributes as you need. The more the better.
32	*
33	* @example
34	*
35	* Log::error( 'Error message', [
36	* 'category' => 'Payment',
37	* 'source' => 'Stripe add-on',
38	* 'donation_id' => $donationId,
39	* 'donor_id' => $donorId
40	* ] );
41	*
42	* @note You can use an array or object as a context attribute value.
43	*
44	* @example
45	*
46	* try {
47	* something();
48	* } catch ( Exception $exception ) {
49	* Log::error( 'Something went wrong', [
50	* 'exception' => $exception,
51	* 'additional_info' => [
52	* 'donation_id' => $donationId
53	* ]
54	* ] );
55	* }
56	*
57	*
58	* @method static void error(string $message, array $context = [])
59	* @method static void warning(string $message, array $context = [])
