Merge branch 'develop'
Updated xcodeproj workspace defs. Somehow not included previously?
Updated track/progress to use CAShapeLayers; refactored as layout function rather than draw function. Animated.
Refactored calls as layout not draw, updated labels on style changes, updated demo project, code cleanup.
Merge branch 'feature/animated-track-and-progress' into develop
Fixed missing outlets in ipad demo, added valueText to setProgress.
