AddExample              Add an example to an existing PowerPlot or
                        GridPlot
ArraySlicer             Cut slice from array (typically of class
                        'power_array')
Example                 Find combination of parameters required for
                        achieving a desired power (or other objective).
FindTarget              Find requirements for target power (or other
                        objective)
GridPlot                Plot requirements for achieving a target power
                        as a function of assumptions about two
                        parameters
PowerDF                 Transform power_array into power_df
PowerGrid               Evaluate function (iteratively) at a grid of
                        input arguments
PowerPlot               Plot the relation between assumed parameters
                        and requirements for achieving a target power
                        (or other objective)
Refine                  Refine or extend the result of PowerGrid
SummarizeIterations     Summary of object that has individual
                        iterations saved.
