SSA-enabling Instructions

As long as BlockSSALEFT $=$ TRUE, LEFT will be protected from evaluations and restorations by SSA. This is important to allow for (1) complex learning processes computing not just one but many correlated modifications of LEFT-columns, and (2) reward delays: using the EnableSSALEFT() instruction below, LEFT can influence when to trigger evaluations and when to wait for delayed reward.

EnableSSALEFT($x_1$): If $x_1 < 10$ (the value 10 is chosen arbitrarily) then set BlockSSALEFT $=$ FALSE.

EnableSSARIGHT($x_1$): analogous to EnableSSALEFT.
