Begin customisation styles.
Add peek button to show the character sets.
Turn off peeking when resetting or positioning.
Move options setting to base view.
Ensure slider chars don't interrupt touch events.
Store finger data in localStorage.
Ensure initial character is newly selected when loaded from localStorage.
Remove padding from body so positioning works against 0,0.
Allow positions and rotations of fingers to be set by user.

On first initialize of the app, a drag determines the position and
rotation of all five fingers, from thumb through pinky. The position
is from the touchstart coordinates, and the rotation is determined
by the path drawn by the user's finger.
Ensure app picks up from last positioned finger if quit/refreshed.
Add banner comments to more easily navigate long JS file.
