Update 1.0.1

Changelog 1.0.1:

-Added "GetBorderEdgesOfSetOfTiles"-method which just as the name says returns all border edges of a collection of tiles - i.e. all edges where one of  the adjacent tiles is part of the collection and one isn't. This is mostly useful for visualisation, e.g. showing where a unit can move within one turn or area of influence of an effect.

-Added unit-tests for HexConverter class, unit-tests for Hex and HexUtilityClass still missing.

-Cleaned up some comments and marginally improved XML-comments for some methods.

-Added proper Attribution to Amit Patel in Example selection screen.
