Add option for shaded area to intercept and ignore all interactions.

(As titled). Effectively, this would allow actions only to occur through the highlighted area.

Edit: This would need to be optional per stage of the tutorial. Example use case:

• In the first tutorial stage, a label saying "Click anywhere to begin tutorial" is shown. This stage would accept a tap action regardless of the position tapped on the screen (as standard).

• In the next stage, a highlight appears around a button; the user must press within this area (ideally, a genuine tap of the button should be required, but we can create the illusion of it programmatically, so it's not a big problem) to continue; any taps elsewhere would not advance the tutorial to the next stage.

Suggested interface:

/**
 This optional method returns whether, for any given index, the tutorial should advance only upon taps made INSIDE the highlighted area (TRUE) rather than anywhere in the whole tutorial area (FALSE; default value).
 */
-(BOOL)tutorialRestrictActionsToWithinHighlight:(NSInteger)index;

This was fixed in version 1.3! Please see updated README file.
