Detailed Description

This class encapsulates "magic words" such as "#redirect", NOTOC, etc.

Usage:
if (MagicWord::get( 'redirect' )->match( $text ) ) {
// some code
}

Possible future improvements:

Please avoid reading the data out of one of these objects and then writing special case code. If possible, add another match()-like function here.

To add magic words in an extension, use $magicWords in a file listed in $wgExtensionMessagesFiles[].

Example:
$magicWords['en'] = [
'magicwordkey' => [ 0, 'case_insensitive_magic_word' ],
'magicwordkey2' => [ 1, 'CASE_sensitive_magic_word2' ],
];

For magic words which are also Parser variables, add a MagicWordwgVariableIDs hook. Use string keys.
