Full sat-nav mode

[mvl22]

This is the master ticket for the addition of a full sat-nav mode rather than a journey planner app.

Already being requested by users, quite naturally.

Implementation steps:

• Set user geolocation to be at a fixed point, and move the map position (would be useful mode anyway)
• Add satnav mode switching (so old mode is still available)
• Add maths to rotate tiles in opposite angle to device angle (or use Vector display - library vendor contacted about this)
• Add fogging to prevent infinite distance
• Add way to detect which part of the route user is on (maths)
• Issue turn alert
• Add replan mode if user goes far off route

Key issues are:

• Retain itinerary mode?
• Show 'Turn left' rather than individual route sections
• Is the iPhone GPS fast enough to recognise the user's location?
• How to deal with "Take the fourth sideroad on the left"

Continuing to get requests for this.

Really should be a vector mode product.

Committed a first cut that I wrote on the train this morning. Cycled from Euston to Waterloo (admittedly a route a do all the time) and it worked really well. Quite pleased.

Needs quite a lot of polish - speech, keeping screen on, upcoming turns, UI changes, all that stuff, but it's on the way.

Awesome - can't wait to try it!
