-/**
- * TAuthorizationRule class
- *
- * TAuthorizationRule represents a single authorization rule.
- * A rule is specified by an action (required), a list of users (optional),
- * a list of roles (optional), a verb (optional), and a list of IP rules (optional).
- * Action can be either 'allow' or 'deny'.
- * Guest (anonymous, unauthenticated) users are represented by question mark '?'.
- * All users (including guest users) are represented by asterisk '*'.
- * Authenticated users are represented by '@'.
- * Users/roles are case-insensitive.
- * Different users/roles are separated by comma ','.
- * Verb can be either 'get' or 'post'. If it is absent, it means both.
- * IP rules are separated by comma ',' and can contain wild card in the rules (e.g. '192.132.23.33, 192.122.*.*')
