	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
