+
+
+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.
