WIP - Text View Cell implementation not working
Demo Project now includes 'ALTextFieldCell', 'ALTextFieldOnlyCell', 'ALTextViewCell', and 'ALTextViewOnlyCell'.
Minor bug fixes for 'ALTextViewCell' subtitle constraints.
Minor fix for method name in header file
Merge branch 'master' of https://github.com/JRG-Developer/AutoLayoutCells into TextFieldDemo
- Changed bottom constraint priority to `999` on `textView` of `ALTextViewCell.xib` and `ALTextViewOnlyCell.xib`. This way, auto layout doesn't break constraints when the height changes.
- Organized code and simplified logic in various places.
- Added missing MIT license comment headers.
