Detailed Description

graph sharing management We use a graph to manage graph sharing if (v->u) E, user v shares data to user u (v, u).share_graph gives a string of all graph names v sharing to u

manage users of gShell and dynamically allocate services In this mode, all gShell services should be delegated by a superuser
