* Changed files imported from VS to lower-case file names. Closes #5.
* Reorganized world generation - made more specialized functions to increase readability (hopefully).
* Created and implemented (fully) a Grid type. Closes #6.
* Worked a bit on issue #7. Simplified the code, but didn't really improve the algorithm's performance yet. Implementing the Grid type also helped a lot in readability and a bit in performance. Free lunch is always nice.
* Tomorrow issue #1 will be closed!
