+These classes generate 2D arrays of integers that have various interpretations. The main purpose of these

+template-based and so they take care of the underlying sizes automatically. This makes them easier to chain
+and re-chain, since the size parameters don't need to be adjusted after each such case. Their performance is,
+however, slightly worse, which is why we use cIntGen classes in the final generator.

+Because there is no SizeX / SizeZ template param, the generators would have to either alloc memory for each
