In weeks DVC:
The scrollview now scrolls aptly when a textfield is selected or exited
Return key is set to next/done key according to the active textfield, and they perform their functions appropriately.
storyboard: changed background colour of scrollable part of the form weeks DVC to white, added the integrated graph VC

Integrated graph VC: The new scrollable graph VC!! ^^ uses custom made uiscrollview. Diagonal scrolling is disallowed by codes in UIScrollViewDelegate methods. Using fake data for now!
Added 2 tap recognizers to the graph scrollView. double tap tends to produce single tap. hope  it works out! (:
...work in progress with ZY...
