Added reachability test support using Apple's reachability class. Doesn't seem to work... Will be trying another Reachability class.
Reachability:
Reachability is removed since it doesn't work. Tried another Reachability lib, but it doesn't seem to work too. Will have to implement own library.

Integrated GVC:
HUD added to scrollView. And end-of-graph-plotting notification system is now revamped to make the code cleaner.
Memory management needs to be made more intelligent in cases of fast scrolling over many pages.
Standing balance not done yet.
Solved text-field changing bug in activities TVC that caused perpetual HUD.
Fixed bugs in Integrated GVC that caused crashes in cases of plotting single row of graph views.
