Membrane currencies are used to establish circles by forming a context that names currencies and users, and then assigning users to roles (player_classes) in the circle's currencies.<br />
Player classes: self (represents the circle as a whole), member (users names in the circle), namer (the stewards responsible for adding users and currencies to the circle)<br />
Self Summary functions: Currencies--The list of currencies used by the circle<br />
Self Plays:
-- none yet --
Member Summary function: Permissions--The list of permissions a member has.<br />
Member Plays:
-- none yet --
Namer Summary Function: none
Namer Plays:
bind_currency(from,to,currency,name,meta) # adds a currency to the circle to be known as name.
unbind_currency(from,to,currency,name) # adds a currency to the circle to be known as name.
name_member(from,user,name) # names a new member player into the circle as for a user.
grant(from,to,currency,player_class) # adds a member of the circle to a currency as a given player_class.
revoke(from,to,currency,player_class)
