Growth
hideGrowth refers to an increase in some quantity over time. The quantity can be physical (e.g., growth in height, growth in an amount of money) or abstract (e.g., a system becoming more complex, an organism becoming more mature). It can also refer to the mode of growth, i.e. numeric models for describing how much a particular quantity grows over time.
