created a constructor for grid
finished adding initial traversing logic
added unit tests, because Opening a window is to much work to test simple logic
added a method to get the size
added a bunch of simple tests
made accesors public
switched from a 2 dimensinal map to a one dimensional array and some calculations... This method is easier to understand, and produces less bugs, while it probably is faster
now the code actualy builds, however the unit tests still fail
unit tests now build
