/**
* Minimal tomcat starter for embedding/unit tests.
*
* Tomcat supports multiple styles of configuration and startup - the most common and stable is server.xml-based,
* implemented in org.apache.catalina.startup.Bootstrap.
*
* This class is for use in apps that embed tomcat.
*
* Requirements:
*
* - all tomcat classes and possibly servlets are in the classpath. (for example all is in one big jar, or in eclipse
* CP, or in any other combination)
* - we need one temporary directory for work files
* - no config file is required. This class provides methods to use if you have a webapp with a web.xml file, but it
* is optional - you can use your own servlets.
*
*
* There are a variety of 'add' methods to configure servlets and webapps. These methods, by default, create a simple
* in-memory security realm and apply it. If you need more complex security processing, you can define a subclass of
* this class.
*
* This class provides a set of convenience methods for configuring web application contexts; all overloads of the
* method addWebapp(). These methods are equivalent to adding a web application to the Host's appBase
* (normally the webapps directory). These methods create a Context, configure it with the equivalent of the defaults
* provided by conf/web.xml (see {@link #initWebappDefaults(String)} for details) and add the Context to a
* Host. These methods do not use a global default web.xml; rather, they add a {@link LifecycleListener} to configure
* the defaults. Any WEB-INF/web.xml and META-INF/context.xml packaged with the application will be processed normally.
* Normal web fragment and {@link jakarta.servlet.ServletContainerInitializer} processing will be applied.
*
* In complex cases, you may prefer to use the ordinary Tomcat API to create webapp contexts; for example, you might
* need to install a custom Loader before the call to {@link Host#addChild(Container)}. To replicate the basic behavior
* of the addWebapp methods, you may want to call two methods of this class: {@link #noDefaultWebXmlPath()}
* and {@link #getDefaultWebXmlListener()}.
*
* {@link #getDefaultWebXmlListener()} returns a {@link LifecycleListener} that adds the standard DefaultServlet, JSP
* processing, and welcome files. If you add this listener, you must prevent Tomcat from applying any standard global
* web.xml with ...
*
* {@link #noDefaultWebXmlPath()} returns a dummy pathname to configure to prevent {@link ContextConfig} from trying to
* apply a global web.xml file.
*
* This class provides a main() and few simple CLI arguments, see setters for doc. It can be used for simple tests and
* demo.
*
