_hasPermission

Produces true if the current user has the named permission on the received Thing -- Function
THING -> _hasPermission(PERMISSION._self) -> true or false
Permission should be any Permission Property, such as Can Edit or Can Have User Values. It is usually safe to assume that the current user Can Read, since they have already gotten to this point.
Note that you must include "._self" after the Permission's name, at least for the time being.
This is typically used in _filter or _if.
