+ * The value for the key "construct" (or Co_CON_SPEED) is the multiplier for construction delay.
+ * The value for the key "deconstruct" (or Co_DECON_SPEED) is the multiplier for deconstruction delay, in case you hadn't guessed.
+ * If one is zero, the tool cannot be used in that direction. If you want to adminbus an instant tool, use .0001 or something, not 0.
+ * Don't set either to a negative number. It will probably break, though I'm not really sure in what way.
+ * Since this is a variable of /atom, it can technically be applied to any item used in construction, as long as the construction is based on construction datums.
+ * Yes, this allows for hyperspeed building stacks, but I wouldn't recommend that, as it doesn't carry over too well when stacks are merged or separated.
+ * Might work for borg stack modules, though. Worth looking into.
