 Roles

-The purpose of roles is to offer a more precise permission management and remain independent on the user name. As soon as user logs in, he is assigned one or more roles. Roles themselves may be simple strings, for example, `admin`, `member`, `guest`, etc. They are specified in the second argument of `Identity` constructor, either as a string or an array.

-As you already know, logging the user out does not erase his identity. Thus, method `getIdentity()` still returns object `Identity`, including all granted roles. The Nette Framework adheres to the principle of "less code, more security", so when you are checking roles, you do not have to check whether the user is logged in too. Method `isInRole()` works with **effective roles**, ie if the user is logged in, roles assigned to identity are used, if he is not logged in, an automatic special role `guest` is used instead.
