I've been busy lately with refactoring the code.
After finishing the first version of the code conventions (everybody has one, so why isohexengine having one, right?), I've started applying it to the code. This required rewriting most of the code and, even though most of this was mostly moving the code around, creating new namespaces, reindenting and renaming data members, it still got more than I have expected.
But the changes are almost done, so I will be soon able to concentrate on new things again. And the code looks a bit better and has a bit more doxygen comments.
Expect a new isohexengine in a week or so :)
