   Create markup for a table used to set filters to use when selecting
   courses in a domain.  Used by lonpickcourse.pm, lonmodifycourse.pm
   and quotacheck.pl
   
   
   Inputs:
   
   filterlist - anonymous array of fields to include as potential filters
   
   crstype - course type
   
   roleelement - fifth arg in selectcourse_link() populates fifth arg in javascript: opencrsbrowser() function, used
                 to pop-open a course selector (will contain "extra element").
   
   multelement - if multiple course selections will be allowed, this will be a hidden form element: name: multiple; value: 1
   
   filter - anonymous hash of criteria and their values
   
   action - form action
   
   numfiltersref - ref to scalar (count of number of elements in institutional codes -- e.g., 4 for year, semester, department, and number)
   
   caller - caller context (e.g., set to 'modifycourse' when routine is called from lonmodifycourse.pm)
   
   cloneruname - username of owner of new course who wants to clone
   
   clonerudom - domain of owner of new course who wants to clone
   
   typeelem - text to use for left column in row containing course type (i.e., Course, Community or Course/Community)
   
   codetitlesref - reference to array of titles of components in institutional codes (official courses)
   
   codedom - domain
   
   formname - value of form element named "form".
   
   fixeddom - domain, if fixed.
   
   prevphase - value to assign to form element named "phase" when going back to the previous screen
   
   cnameelement - name of form element in form on opener page which will receive title of selected course
   
   cnumelement - name of form element in form on opener page which will receive courseID  of selected course
   
   cdomelement - name of form element in form on opener page which will receive domain of selected course
   
   setroles - includes access constraint identifier when setting a roles-based condition for acces to a portfolio file
   
   clonetext - hidden form elements containing list of courses cloneable by intended course owner when DC creates a course
   
   clonewarning - warning message about missing information for intended course owner when DC creates a course
   
   
   Returns: $output - HTML for display of search criteria, and hidden form elements.
