/**
* this page defines what roles can access (grant user that role and override that roles'
* capabilities in different context. For example, we can say that Teachers can only grant
* student role or modify student role's capabilities. Note that you need both the right
* capability moodle/role:assign or moodle/role:manage and this database table roles_deny_grant
* to be able to grant roles. If a user has moodle/role:manage at site level assignment
* then he can modify the roles_allow_assign table via this interface.
