/**
* Provides a widget for group selection select boxes.
*
* This widget is configurable with the following options:
*
* groupfilter: regular expression to filter available groupsgroups: comma separated list of group names to show in the select box. Note:
* if this configuration option if used,
* groupfilter and includesubous are not considered anymore.includesubous: boolean flag to indicate if sub OUs should be scanned for groups to selectoufqn: the fully qualified name of the OU to read the groups from
* To map the selected group to a permission to set, use the following mapping configuration:
* <mapping element="..." mapto="permission:GROUP:+r+v|GROUP.ALL_OTHERS:|GROUP.Projectmanagers:+r+v+w+c" />
* This means that the +r+v permission is written for the principal GROUP on the resource.
* Additionally two permissions are written as default: for ALL_OTHERS, no allowed permission is set,
* for Projectmanagers, "+r+v+w+c" is set.
*
* @since 8.0.0
