+These classes generate 2D arrays of integers that have various interpretations. The main purpose of these
+classes is to provide fast prototyping for cIntGen classes - unlike cIntGen classes, these are not
+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
+underlying generator's values, or use a maximum-size buffer. We chose the latter, to avoid memory allocation
+overhead; this however means that there's (an arbitrary) limit to the size of the generated data.
