Removed some unneccessary code and comments from PolarParser.parse(...).

Fixed a bug where the polar parser would attempt to insert (wind speed, windspeed, windangle) instead of (windspeed, windangle, boatspeed).
Removed some unused constructors from RaceXMLReader, and fixed a bug where it wouldn't actually use the polar table correctly.
Boat's constructor now expects a Polars table.
Added some comments to the Polars class, and specified the HashMap's template parameters
Added PolarsTest - which needs to be implemented properly when the VMG calculations have been added.
