<DD>Performs all initialization steps that need to be performed
 before any subclass initialization is performed.

 <p/>Classes that override this method should always call
 <code>super.initFirst()</code> <strong>before</strong> doing
 any of their own work.

 This method loads and initializes all modules
 described in the given implementation advertisement. Then, all modules
 are placed in a list and the list is processed iteratively. During each
 iteration, the <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A> method of each module
 is invoked once. Iterations continue until no progress is being made or
 the list is empty.

 <p/>The status returned by the <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A> method
 of each module is considered as follows:

 <ul>
 <li><A HREF="../../../../net/jxta/platform/Module.html#START_OK"><CODE>Module.START_OK</CODE></A>: The module is removed from the list of
 modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will not be invoked again.
 </li>

 <li><A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_PROGRESS"><CODE>Module.START_AGAIN_PROGRESS</CODE></A>: The module remains in the
 list of modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will be invoked during the next iteration, if there is one. </li>

 <li><A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_STALLED"><CODE>Module.START_AGAIN_STALLED</CODE></A>: The module remains in the list
 of modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will be invoked during the next iteration if there is one. </li>

 <li>Any other value: The module failed to initialize. Its
 <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will not be invoked again.</li>
 </ul>

 <p/>Iterations through the list stop when:
 <ul>
 <li>The list is empty: the group initialization proceeds.</li>

 <li>A complete iteration was performed and all modules returned
 <A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_STALLED"><CODE>Module.START_AGAIN_STALLED</CODE></A>: a <A HREF="../../../../net/jxta/exception/PeerGroupException.html" title="class in net.jxta.exception"><CODE>PeerGroupException</CODE></A>
 is thrown.</li>

 <li>A number of complete iteration completed without any module
 returning <A HREF="../../../../net/jxta/platform/Module.html#START_OK"><CODE>Module.START_OK</CODE></A>: a <A HREF="../../../../net/jxta/exception/PeerGroupException.html" title="class in net.jxta.exception"><CODE>PeerGroupException</CODE></A>
 is thrown. The number of complete iterations before that happens is
 computed as 1 + the square of the number of modules currently in the
 list.</li>

<DL>
<DD>Returns the all purpose peer group implementation advertisement.
 This defines a peergroup implementation that can be used for
 many purposes, and from whih one may derive slightly different
 peergroup implementations.
 This definition is always the same and has a well known ModuleSpecID.
 It includes the basic service, no protocols and the shell for main
 application.
 The user must remember to change the specID if the set of services
 protocols or applications is altered before use.
