 * Enumerates the possible access levels to a page. In order of priority:
 * 
 *     NONE - neither grants, nor forbids access.
 *     VIEW - grants access to the page in read-only mode.
 *     EDIT - grants access to the page in edit mode: some operations are permitted
 *     (depending on the type of page), but at least modifying the Groovy source code of the page is forbidden.
 *     DEVELOP - grants every permissions except those reserved for the administrator
 *     (superuser), including that of editing the Groovy source code of the page.
 *     DENY - denies access to the page.
 * 
 *
 * The level with the greatest priority wins over the others.
