Roles Permissions Matrix

The following table represents the proposed association b/w roles and permissions in doccano. Currently, roles are not implemented so following permissions are not used during authorization.

Doccano does rely on Django default permissions <> and also extend them to perform user authorization. This is explained in a later section titled "Authorization in Doccano"

Permissions(P) are represented by the rows and Roles(R) by the columns.
