file_permissions.db now stores information for each file as an array of arrays and a hash. In the hash, keys can either be accesscount or access. For key = access value is an anonymous hash containing key=value pairs defining access controls. For key = accesscount, value is a scalar (integer to be used when creating the next accesscontrol). Documentation added.
