/**
 * Course category level icon modification.
 *
 * Please refer to "modicons.php" for a detailed explanation of what actions are performed.
 * The difference is in the storage; this is COURSE level.
 *
 * What does this do? In simple terms:
 * - display a form with one upload field per activity _type_.
 *   ALL activitity types are shown, not just those used in the course.
 * - store each (btw completely optional) image in mdl_files under the coursecategory
 *   context with component 'format_vsf', filearea 'modicon_<mod>', itemid 0.
 * Please note the filearea specialisation!
 * So storage is the exact same as for syscontext with the exception of... the contextid
 *
