+/// at the end of the tick. This results in the formulation of values that are
+/// roughly analgous to prices for each commodity. The workforce is then
+/// reassigned according to the respective commodity values. The simulation also
+/// includes damping terms that prevent cyclical inconsistencies in value
+/// rationalisation magnifying enough to crash the economy. We also ensure that
+/// a small number of workers are allocated to every industry (even inactive
+/// ones) each tick. This is not an accident: a small amount of productive
+/// capacity in one industry allows the economy to quickly pivot to a different
+/// prodution configuration should an additional commodity that acts as
+/// production input become available. This means that the economy will
+/// dynamically react to environmental changes. If a product becomes available
+/// through a mechanism such as trade, an entire arm of the economy may
+/// materialise to take advantage of this.
