/**
 * This class implements the Compound interface because it can "contain" Virtual Hosts components. The Apache interface
 * is the Remoteable interface and the Runnable interface is used to monitor the httpd process. The httpd process is
 * started in sfStart by setting the apacheState variable to true and ended in sfTerminate by setting the apacheState
 * variable to false. The Internet Activator scripts are used to edit the httpd.conf file. These rely on certain
 * environment variables being set, these variables are defined in the sf file and are passed to the
 * common.executeScript() method. Adding them to the sf file avoids the need to hard code these paramters. The scripts
 * are downloaded from a webserver and are then saved locally.
