- Added an .h file for more convenient imports
- Added tab bar separators (with a colour property that can be modified at the container level)
- Inset the indicator bar by 10 px on each side
- Doubled the height of the indicator bar and separator bar
- Modified selection scrolling behaviour to be limited by content size of tab bar buttons
- Added tab selection method (only works if called after all the containers views are laid out, unfortunately)
