   # Note from Jeremy 5-8-2003: It is *vital* that the real handler be called
   # as a subroutine from the handler, or very mysterious things might happen.
   # I don't know exactly why, but it seems that the scope where the Apache
   # server enters the perl handler is treated differently from the rest of
   # the handler. This also seems to manifest itself in the debugger as entering
   # the perl handler in seemingly random places (sometimes it starts in the
   # compiling phase, sometimes in the handler execution phase where it runs
   # the code and stepping into the "1;" the module ends with goes into the handler,
   # sometimes starting directly with the handler); I think the cause is related.
   # In the debugger, this means that breakpoints are ignored until you step into
   # a function and get out of what must be a "faked up scope" in the Apache->
   # mod_perl connection. In this code, it was manifesting itself in the existence
   # of two seperate file-scoped $helper variables, one set to the value of the
   # helper in the helper constructor, and one referenced by the handler on the
   # "$helper->process()" line. The second was therefore never set, and was still
   # undefined when I tried to call process on it.
   # By pushing the "real handler" down into the "real scope", everybody except the 
   # actual handler function directly below this comment gets the same $helper and
   # everybody is happy.
   # The upshot of all of this is that for safety when a handler is  using 
   # file-scoped variables in LON-CAPA, the handler should be pushed down one 
   # call level, as I do here, to ensure that the top-level handler function does
   # not get a different file scope from the rest of the code.

 =head2 Element Base Class  =head2 Element Base Class
   
 The Apache::lonhelper::element base class provides support methods for  The Apache::lonhelper::element base class provides support for elements
 the elements to use, such as a multiple value processer.  and defines some generally useful tags for use in elements.
   
 B<Methods>:  
   
 =over 4  
   
 =item * process_multiple_choices(formName, varName): Process the form   B<finalcode tag>
 element named "formName" and place the selected items into the helper   
 variable named varName. This is for things like checkboxes or   
 multiple-selection listboxes where the user can select more then   
 one entry. The selected entries are delimited by triple pipes in   
 the helper variables, like this:    
   
  CHOICE_1|||CHOICE_2|||CHOICE_3  Each element can contain a "finalcode" tag that, when the special FINAL
   helper state is used, will be executed, surrounded by "sub { my $helper = shift;"
   and "}". It is expected to return a string describing what it did, which 
   may be an empty string. See course initialization helper for an example. This is
   generally intended for helpers like the course initialization helper, which consist
   of several panels, each of which is performing some sort of bite-sized functionality.
   
   B<defaultvalue tag>
   
   Each element that accepts user input can contain a "defaultvalue" tag that,
   when surrounded by "sub { my $helper = shift; my $state = shift; " and "}",
   will form a subroutine that when called will provide a default value for
   the element. How this value is interpreted by the element is specific to
   the element itself, and possibly the settings the element has (such as 
   multichoice vs. single choice for <choices> tags). 
   
   This is also intended for things like the course initialization wizard, where the
   user is setting various parameters. By correctly grabbing current settings 
   and including them into the helper, it allows the user to come back to the
   helper later and re-execute it, without needing to worry about overwriting
   some setting accidentally.
   
 =back  Again, see the course initialization helper for examples.
