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

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 10km. Cache size is 17.

Threshold for building the cache was 93%.

Point furthest from the centre of cache (26000000, 08000000) is 2741433, 0674083; distance away is: 18.9095 kilometres.
