New map for user test

During this week, we revised maps based on tutor's feedback:

- Route line angle: define the directions (straight direction or "V" direction)
- Shopping area color: we should change the current colour (green reminds to park)
- Churches: we should take into account the churches in the city centre (turist attraction)
- Icons: the museum icons should have "columns" inside
- The museum areas shouldnt be totally coloured in purple

- The tutor appreciated the brightness/sharpness style of the icons
