	=item * &excess_filesize_warning()

	Returns warning message if upload of file to authoring space, or copying
	of existing file within authoring space will cause quota for the authoring
	space to be exceeded.

	Same, if upload of a file directly to a course/community via Course Editor
	will cause quota for uploaded content for the course to be exceeded.

	Inputs: 7
	1. username or coursenum
	2. domain
	3. context ('author' or 'course')
	4. filename of file for which action is being requested
	5. filesize (kB) of file
	6. action being taken: copy or upload.
	7. quotatype (in course context -- official, unofficial, community or textbook).

	Returns: 1 scalar: HTML to display containing warning if quota would be exceeded,
	otherwise return null.

	=head1 Routines for building display used to search for courses


	=over 4

	=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

	Process selected filters form course search form and pass to lonnet::courseiddump
	to retrieve a hash for which keys are courseIDs which match the selected filters.

	Inputs:

	dom - domain being searched

	type - course type ('Course' or 'Community' or '.' if any).

	filter - anonymous hash of criteria and their values

	numtitles - for institutional codes - number of categories

	cloneruname - optional username of new course owner

	clonerudom - optional domain of new course owner

	domcloner - Optional "domcloner" flag; has value=1 if user has ccc priv in domain being filtered by,
	(used when DC is using course creation form)

	codetitles - reference to array of titles of components in institutional codes (official courses).


	Returns: %courses - hash of courses satisfying search criteria, keys = course IDs, values are corresponding colon-separated escaped description, institutional code, owner and type.
