Adam Rocska a3eaa2b8c9 MaxMind Iterator is done.

Adam Rocska f97ca19be5 Iterator in progress. The concept is good enough, just has to be polished.

Adam Rocska 3f4914190d A strategy emerged on how to process MaxMindDB data. May not be the best, but it could work.

Adam Rocska 6449c653b2 It works. The motto should still remain "RTFM". Signed integers arrive as two's complement instead of signed magnitude (duh).

Adam Rocska a9dd03de70 Simplified the inlined type cast state. Now it's time to try the integer sign part.

Adam Rocska bee57f211a Last try before dumping & preconditioning: Moved the typed value contruction into the padding & truncating functions. Here the integer signed cases could be handled properly.

Adam Rocska 438c0eca44 Doing a commit, to save the state. But will remove truncation logic at all, and just simply set a precondition. MaxMind's DB format could possible have an "overflow case" happen, but it just won't be supported.

Adam Rocska 92806b035d I really needed these limitedIndex accessors. I don't know if it's an anti-pattern with Swift or not, but I couldn't find another way around.
