+   IdentityScope represents a scope of an identity. IdentityScope 
+   is also an Identity and can have a name and scope along with 
+   the other qualitites identities posses.

+   An IdentityScope contains other Identity objects. All Identity 
+   objects are manipulated in the scope the same way. The scope 
+   is suppose to apply different scope to different type of 
+   Identities.
+
+   No identity within the same scope can have the same public key.
