/**
* Core interfaces and exceptions supporting Authorization (access control).
* <p/>
* Shiro abbreviates the word 'AuthoriZation' as <tt>authz</tt> to distinguish it separately from
* 'AuthentiCation', abbreviated as <tt>authc</tt>.
* <p/>
* This package's primary interface of interest, which is the core of Shiro authorization functionality,
* is the <tt>Authorizer</tt>. This interface handles all aspects of principal-related security and is the
* facade to all other Shiro authorization components.
* <p/>
* Shiro has the ability to authorize subjects (a.k.a. users) without being intrusive to the application's
* domain model. Most applications will utilize the concepts of <tt>group</tt>s, <tt>role</tt>s, and
* <tt>permission</tt>s, but Shiro tries to be as non-invasive as possible doesn't require any such
* interfaces (although a Permission interface is made available for fine-grained access control policies if
* you want to use Shiro's permission support out-of-the-box).
* <p/>
* Although it is possible for applications to implement this and other interfaces directly, it is not
* recommended. Shiro already has base implementations which should be suitable for 99% of deployments.
