that starts at x0 at time t=0, (NB x must satisfy 0<x0<1)~
then grows nearly exponentially increasing by g each time period,~
and finally flattens out as x approaches 1.~
It uses a logistic function.~
~
This is useful for such things as growth in market share that cannot exceed 100%. If you want the result to have a maximum m different from 1, e.g. the total market size, then simply use the product "M*S_growth(x0,g,t)"
