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.

For example, the most obvious component accessible via an {@code Environment} instance is the application's
{@link #getSecurityManager() securityManager}.
