Block and space inheritability

[SeanMcOwen]

• Some of the examples made me think about how we might have a very abstract space of PlayerResponse, but then it may be that there are more refined version of player response that correspond to different kinds of player responses (in terms of the data)
• If we allow inheritance at the block level (the abstract level) it might let us do something like say that a 2 player game has these spaces but our more refined version of it fulfills them even when the spaces might be CartesianPlanePlayerResponse which inherits from PlayerResponse space
• But this might be going to deep into it, so mostly just pinning it here for future
