-  // This library handles subscriptions by running the "Subscribe" function which should return a channel, and a "Resolve" function which returns the new value to send to the client
-  /*
-  Library modifications required:
-    1) Make the last result available in the ResolveContext
-    2) When resolving, check if the current field exists in the previous result, using the previous result instead of re-resolving(only resolve fields that don't exist in the previous result)
-  To make this work with graphvent:
-  1) In Subscribe:
-    - Make a channel for the gql extension to forward messages to this context
-    - Send the read request associated with the root of the subscription
-  2) In Resolve:
-    - If the incoming message is a read result, process it as the new root result
-    - If the incoming message is a status, delete all the nodes found from the root that have the same NodeID and re-resolve
