Do not merge this pull request, I merely used this as a convenient way to comment :-)
Below are some first thoughts I had when looking through the source code. In general I find the code relatively simple to read (which is very good), but there is room for improvement regarding the structure of the overall program. For example you currently implement everything in header files, with just a single source file (main.cpp) including all of the headers. Was this a conscious decision, or would you be fine spliting them into header/source file pairs? That would allow for a better documentation of the individual functions.
Overall my comments below are not as important as the ones I raised in #2, and #2 should be addressed first before addressing the comments in this pull request.
