/**
* A <b>Context</b> is a Container that represents a servlet context, and
* therefore an individual web application, in the Catalina servlet engine.
* It is therefore useful in almost every deployment of Catalina (even if a
* Connector attached to a web server (such as Apache) uses the web server's
* facilities to identify the appropriate Wrapper to handle this request.
* It also provides a convenient mechanism to use Interceptors that see
* every request processed by this particular web application.
* <p>
* The parent Container attached to a Context is generally a Host, but may
* be some other implementation, or may be omitted if it is not necessary.
* <p>
* The child containers attached to a Context are generally implementations
* of Wrapper (representing individual servlet definitions).
* <p>
