Added an attribute to each yacht: 'DistanceToNextMark'

This attribute is calculated at each update of the boat as prompted by the game state regularly
Removed the lat and lng attribute from the Yacht class and replaced its usage with the GeoPoint object instead

Removed redundant test files and merged GeoUtility and testGeoUtil test classes into one
