Test with starting point at Dartmoor using default (linear) matching algorithm and cache size 20

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 3km. Cache size is 20. (Size is set as a fixed value, derived from original size of 89).

Point furthest from the centre of cache (25300000, 07300000) is 2472222, 0543386; distance away is: 19.5788 kilometres.
