Updated Frame task and glm task to reduce cost of transporting data info over network (removed adaptedFrame before sending over, not sending data info back at all, only one copy of data info in LineSearchTask).
Moved postWrite call in MRTask from postLocal to postGlobal (significant cost since it always fetches rollups of all vecs even if we did not change any of the vecs + if we did, we want to flip the mutating flag when all of mr task is done).
