/**
* Main domain class of forum application representing a discussion forum.
*
* It manages creation of new forum instances and provides getters and setters
* for instance specific configuration options.
*
* XXX: Forum knows about <i>threads</i> which groups a set of posts to the same
* subject, and <i>topics</i> which group a set of threads about the same general
* theme. Currently Forum uses <i>catgegory</i> as synonym for topic, which may be
* misleading in some contexts, because there is <i>forum-categorized</i> which
* uses category in the usual CMS way, esp. navigation categories. Should be
* cleaned up in the future.

/**
* Returns the path name of the location of the applications servlet/JSP.
*
* The method overwrites the super class to provide an application specific
* location for servlets/JSP. This is necessary if you whish to install the
* module (application) along with others in one context. If you install the
* module into its own context (no longer recommended for versions newer
* than 1.0.4) you may use a standard location.
*
* Usually it is a symbolic name/path, which will be mapped in the web.xml
* to the real location in the file system. Example:
* <servlet>
* <servlet-name>forum-main</servlet-name>
* <servlet-class>com.arsdigita.forum.ForumServlet</servlet-class>
* </servlet>
*
* <servlet-mapping>
* <servlet-name>forum-main</servlet-name>
* <url-pattern>/ccm-forum/main/*</url-pattern>
* </servlet-mapping>
*
* @return path name to the applications servlet/JSP
