  * An {@code Environment} instance encapsulates all of the objects that Shiro requires to function.  It is essentially

  * a 'meta' object from which all Shiro components can be obtained for an application.

  * <p/>

  * An {@code Environment} instance is usually created as a result of parsing a Shiro configuration file.  The

  * environment instance can be stored in any place the application deems necessary, and from it, can retrieve any

  * of Shiro's components that might be necessary in implementing security behavior.

  * <p/>

  * For example, the most obvious component accessible via an {@code Environment} instance is the application's

  * {@link #getSecurityManager() securityManager}.
