-=item * &build_filters()
-
-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.
-
-
-Side Effects: None
