Minor debugging tweaks.
Added new cell prototype.
Adjusted height of another prototype.
Trying to make cell states (particularly switches’ states) unique. Currently unfinished.
Removed some outdated comments.
Adjusted some labels in the prototype cells.
Found a possible way to save the state of a cell before it is removed from memory.
Still need to access states of elements in prototype cells in order to save said states.
Additional commit to fix minor bug.
Found a way to set and retrieve the states of controls in each prototype cell using the methods willDisplayCell and didEndDisplayingCell.
Implemented most of the code to handle setting and getting the states of UISwitch controls.
TODO:
	Implement similar code for other cell types.
	Prepare for work on segue between table views.
Changed the naming conventions used for cell types to better reflect that of iOS controls.

Changes:
	LinkingCell -> Linker
	Photo -> Image
	ListBox -> Picker
	CheckBox -> Switch
	TextEntry -> TextField
	TextField -> TextView

So the complete list of cell types currently created is as follows:
	Linker
	Image
	Picker
	Switch
	TextField
	TextView
	Button
Implemented cellState manipulation for the TextField and TextView cells.
Reorganized some code, minor optimizations.
Ready to merge into master branch.
