Test with starting point at Dartmoor using default (linear) matching algorithm and cache size 48

Cache is built using a square with sides 20 km. User's path has steps of (2000, 2000) metres, with a total of 11 retrievals. Amount of look-ahead (both E and N) is 15km. Cache size is 48. (Size is set as a fixed value, derived from original size of 99).

Point furthest from the centre of cache (26500000, 08500000) is 2799935, 0626498; distance away is: 26.903 kilometres.
