   LGTM - overall this is great @Baunsgaard. During the merge, I just fixed a few typos, and minor warnings (generics, static methods).
   
   Additionally, you might want to consider moving the `ColGroupSizes` into the class hierarchy of column groups to avoid string-based dispatching (including abstract classes that could never be instantiated) and bring this closer to their implementation. Also, please reconsider the unnecessary indirection of `AbstractCompressedMatrixBlock` and `CompressedMatrixBlockFactory`. Is there any intention behind them other than splitting `CompressedMatrixBlock` into smaller files?
